Columella's Fig-Rennet Cheese

Making Cheese with The Romans – Columella’s Cheese

Salvete amici!

This ancient recipe is one that I am particularly proud of. It’s challenging and it’s delicious, and there’s nothing I love more than a tasty challenge! Cheese-making is often considered an artisanal craft that is trying, difficult and messy but it’s really not! And we have the Romans (and many other cultures) to thank for teaching us the simplicity of early cheese-making. In this recipe, we are going to meet Columella, an ancient Roman writer and farmer, and have a hands-on introduction to some of the initial stages of his fresh cheese recipe. But before we do… a little bit of history!

Columella’s Cheese – Tavola Mediterranea

Cheese, like bread, has been a staple and a comfort-food in the human diet since time immemorial.  Soft and hard varieties as well as mild and pungent ones make this food item a versatile and pleasing meal additive or enhancer that also stands brilliantly on it’s own with fruit, olives, bread, jellies, herbs and chutneys.  Cheese-making originated long before recorded history with some theories suggesting that it originated in the Middle East and others suggesting it began in eastern Europe during the Neolithic Revolution and the spread of agriculture westward through the Mediterranean. It was during the early Neolithic period that humans began to move from hunter/gatherer lifestyles into the practices of farming, animal husbandry and the keeping of livestock.  With this development they discovered that domesticated animals could also be milked and not just used as a source of meat.

Documentary evidence of cheese-making from ancient Mesopotamia in the form of cuneiform text (circa 2,000 BC) referred to cheese. In Egypt, also from 2,000 BC, funeral murals have also documented butter and cheese-making processes. The earliest material culture indicating cheese-making, however, has been found in Poland and dates to 5,500 BC. By 50 AD, the evidence of cheese making by the Romans was made known in great detail by Columella in his writing De Re Rustica (On Agriculture – 65 AD).  It is this text and Columella’s instructions that we will be following for this recipe.

So who is Columella? Lucius Junius Moderatus Columella (4 BC-70 AD) was a respected Roman farmer and writer who, like Cato, left a great deal of information in the documentary record about early Roman-era farming, agriculture and cooking practices. Columella was a provincial Roman, born in Hispania Baetica (Spain), who also held farm estates in Italy. He wrote a great deal on animal husbandry, farming and pastoral food-preparation in his writings titled De Re Rustica (65 AD) and within this writing comes a great deal of insight into Roman cheese-making.

Columella tells us about cheese-making in De Re Rustica (Book VII, Chapter VIII) in the following passages:

Curds and whey separated using fig rennet

Liber VII: “VIII. Casei quoque faciendi non erit omittenda cura, utique longinquis regionibus, ubi mulctram  
devehere non expedit. Is porro si tenui liquore conficitur, quam celerrime vendendus est, dum adhuc viridis succum retinet : si pingui et opimo, longiorem patitur custodiam. Sed lacte fieri debet sincero et quam recentissimo. Nam requietum vel aqua mixtum celeriter acorem concipit. Id plerumque cogi agni aut haedi coagulo; quamvis possit et agrestisi cardui flore conduci, et seminibus cneci, nee minus ficulneo lacte, quod emittit arbor, si eius virentem saucies corticem. Verum optimus caseus est, qui exiguum medicaminis habet. Minimum autem coagulum recipit sinum lactis argentei pondus denarii. Nee dubium quin fici ramulis glaciatus caseus iucundissime sapiat.

et

Liber VII: “VIII. Nam is, qui recens intra paucos dies absumi debet, leviore cura conficitur. Quippe fiscellis exemptus in salem muriamque demittitur, et mox in sole paulum siccatur. Nonnulli antequam pecus numellis induant, virides pineas nuces in mulctram demittunt, et mox super eas emulgent, nee separant, nisi cum transmiserint in formas coactam materiam. Ipsos quidam virides conterunt nucleos, et lacti permiscent, atque ita congelant. Sunt qui thymum contritum cribroque colatum cum lacte cogant. Similiter qualiscunque velis saporis efficere possis, adiecto quod elegeris condimento. Ilia vero notissima est ratio faciendi casei, quem dicimus manu pressum, Namque is paulum gelatus in mulctra dum est tepefacta, rescinditur et fervente aqua perfusus vel manu figuratur, vel buxeis formis exprimitur. Est etiam non ingrati saporis muria perduratus, atque ita malini ligni vel culmi fumo coloratus.

We can translate from these passages that:

“Book VII: “VIII. It will be necessary too not to neglect the cheese-task of cheese-making, especially in distant parts of making the country, where it is not convenient to take milk to the market in pails. Further, if the cheese is made of a thin consistency, it must be sold as quickly as possible while it is still fresh and retains its moisture; if, however, it is of a rich and thick consistency, it bears being kept for a longer period. Cheese should be made of pure milk which is as fresh as possible, for if it is left to stand or mixed with water, it quickly turns sour. It should usually be curdled with rennet obtained from a lamb or a kid, though it can also be coagulated with the flower of the wild thistle or the seeds of the safflower, and equally well with the liquid which flows from a fig-tree if you make an incision in the bark while it is still green. The best cheese, however, is that which contains only a very small quantity of any drug. The least amount of rennet that a pail of milk requires weighs a silver denarius  and there is no doubt that cheese which has been solidified by means of small shoots from a fig-tree has a very pleasant flavour.”

and:

Book VII: “VIII. Cheese which is to be eaten within a few days while still fresh, is prepared with less trouble; for it is taken out of the wicker-baskets and dipped into salt and brine and then dried a little in the sun. Some people, before they put the shackles on the she-goats, drop green pine-nuts into the pail and then milk the she-goats over them and only remove them when they have transferred the curdled milk into the moulds. Some crush the green pine-kernels by themselves and mix them with the milk and curdle it in this way. Others allow thyme which has been crushed and pounded through a sieve to coagulate with the milk; similarly, you can give the cheese any flavour you like by adding any seasoning which you choose. The method of making what we call ” hand-pressed ” cheese is the best-known of all : when the milk is slightly congealed in the pail and still warm, it is broken up and hot water is poured over it, and then it is either shaped by hand or else pressed into box-wood moulds. Cheese also which is hardened in brine and then coloured with the smoke of apple-tree wood or stubble has a not unpleasant flavour.”

Translation from: Harrison Boyd Ash.

Fig Latex (Sap) for Cheese-Making

Nota Bene (that’s latin for ‘pay attention to the following words!’): What makes this recipe unique and challenging (for those who like to do things the hard way like I do…) is that the coagulant that is used to separate the curd and the whey is EXACTLY as specified by Columella, but it’s not goat or sheep stomach acid (animal rennet)… because I just can’t go there. I just can’t. And I can’t use my usual milk coagulant: lemons, because they weren’t common in the region of Rome or the western Mediterranean until the Middle Ages. So I have used Columella’s other suggestion which is to use fig sap. Who in the dickens would have expected to ever use fig sap in cheese-making? Certainly not me!  But it worked…like a charm. But not in the way that you would expect. I made my own rennet by boiling down the stems of the fig leaves as it was very tricky trying to catch all the white droplets falling from the stems as I ran from my garden into the kitchen with an armful of fig leaves. First, I tried stirring the milk with the severed end of the stems but nothing happened. The milk curdled like a charm, however, after I poured about 3 tbsp of a homemade fig-tree sap and stem reduction (recipe for this is below).

Finally, it is likely that most of you won’t have access to fig trees and will require conventional rennet or another coagulant. If you want to try to stick to the recipe as close as you can, you can try wine vinegar or vegetable rennet (as sold on Amazon) as a coagulant. If you want to just get in there and make the cheese quickly without worrying about authenticity, you can time-travel forward from Columella’s time to the Middle Ages, when lemons began to be used and cultivated in the southwestern Mediterranean, and substitute the fig-sap rennet with the fresh-squeezed juice of a fresh lemon.

For those who may be concerned about the safety of using fig sap or fig-tree stems as rennet, you’re wise to ask this question as I did too. I did a bit of research first and found this article from cheesemaking.com that outlines the historical use of fig sap as rennet and even mentions the stem incision methods that I applied (and thought that I alone had invented! Phooey!) as well as cautions to be taken when handling the sap. It’s noted that some people get skin rashes from handling the sap. I did not, but please wear gloves if you have sensitive skin. It was also noted that fig sap rennet can leave some bitterness in flavour in the cheese. I ate a substantial amount of the cheese before completing this article and noticed a slightly bitter after-taste, but nothing too off-putting. I have not experienced any tummy-aches or other adverse affects from using fig-sap rennet for this recipe. If you would like to err on this side of caution and refrain from trying the fig-sap rennet, please make the right choice for yourself and your famiy and use a conventional rennet, vinegar or lemon.

With that said, let’s roll our sleeves up and make cheese with the Romans!

Making Cheese with The Romans – Columella’s Cheese 

Ingredients

  • 1 gallon (4 litres) of whole goat’s milk (or cow’s milk) – 3.5-4% Milk Fat.
  • 20 fig-leaf stems to make fig rennet (or vegetable rennet)
  • Salt
  • *Optional: Dried mint, walnuts, figs.

 

Implements

  • Colander or basket
  • Cheese cloth
  • Whisk
  • Large pot and small saucepan
  • Kitchen clamp

 

Fig-Sap Rennet (Optional)

  • Stems from 20 fig leaves
Fig Sap Rennet Reduction

To make the fig-sap rennet, cut 20 fig leaves from the tree at the base against the trunk. You’ll see white latex fluid dripping from the base and this is the liquid we are trying to contain. *Use caution in handling the sap if you have sensitive skin. Cut the stems from the leaves and make a lateral slice down the centre of each stem. Place in a saucepan with one cup of water and boil on medium until the water is reduced from 1 cup to approximately 3 tbsp. The water will be opaque by the end of the reduction and will have a distinct herbal tea-like smell to it. Set this rennet aside and use it when it is called for in the recipe.

 

Cheese Preparation

Step 1. Use a large pot to bring your milk to a boil on high. Whisk the milk the entire time to ensure that it doesn’t burn, clump or stick to the bottom of the pot.

Step 2. Wait for it to boil over. It’ll happen at about the 10 minute mark and when it does you want to quickly turn off the element. Make sure that you’re using a deep pot or one that will allow the milk to overboil to almost twice its height without overflowing onto the oven-top.

Step 3. Let the milk stand for 15 minutes.

Step 4. Pour in your choice of rennet and stir it in gently. *If you decide to make the fig rennet, see the instructions above. If you are using vegetable rennet, a teaspoon should do the trick. If you’re using vinegar, a tablespoon will be ample for this recipe. If you’re using lemon, cut the lemon in half and squeeze the juice from both halves into the boiled milk. Let stand for 30 minutes as curds separate from whey.

Step 5. While the milk is separating, get a colander or a basket and some cheese-cloth. Cover the colander with a 2-ply layer for cheese-cloth so that you have enough room on all sides to eventually pull it over the curds. Once it is apparent that the curds and whey have separated, gently pour the liquid into the cloth-lined colander and place it in a pot or in a clean sink. Let stand for an hour until most of the whey has drained out. This may take a while and you don’t want to rush it too much.

Step 6. Once most of the whey has drained, dispose of the whey. Some folks may want to keep it but the rennet flavouring of fig-sap, lemon or vinegar may remain in the whey and may not be too palatable.

Step 7. Grab all corners and edges of the cheese-cloth and gather it over the curds. Twist it and gently squeezing out any remaining whey. Using a kitchen clamp, clamp the top of the cloth to create a tight environment for the curds to further drain, this time under weight. We are going to press our cheese!

Step 8. Under a clean and heavy object in your kitchen (I used my marble mortar) let the curds stand for another hour or so to further drain. By the end of this step, we’ll be ready to wash the curds and salt the cheese. You have the option to serve and eat the cheese at this stage as a fresh ricotta-like soft cheese. It’s beautiful and creamy at this stage. If you’d like to salinate or solidify the cheese, keep following along.

Step 9. For this step, I have decided to take some license and replicate sea-water to make a muria (brine) for washing and salting the curds. My milk is not raw and it is pasteurized so I decided, for simplicity’s sake, to salt brine the cheese instead of age it as Columella describes in other lines of his cheese-making process. Salt was a prime commodity for Romans and it wasn’t always readily available. Apicius used seawater for cooking boar. Sea water was sometimes used by cheese-makers, historically, to salinate and separate curds so I decided to try to replicate that for this salination process; it also firms fresh cheese without having to let it sit and age for a long period of time (Sea water is approximately 3.5% salination so I filled a deep pot with 2 litres (4 cups of water) and 70 ml (5 tbsp of salt) and brought it to a boil). Drop the clamped curds in the cheese-cloth into the boiling salt-water and turn it down to low to simmer for one hour.

Columella’s Cheese

Step 10. Remove the cheese and leave the cheese-cloth and clamp on while placing it in a colander and in the fridge to chill over night.

Step 11. In the morning you will have a firm, crumbly, rich and tangy goat-cheese that can be served with a myriad of complementary pairings. I chose to taste the cheese with Roman foodstuffs that go beautifully with goat-cheese: walnuts, figs, dates, olives and dried mint.

The end result was absolutely amazing. Just the right amount of salt and a crumbly texture much like feta. Once in the mouth it turns creamy and has a beautiful, fresh, open flavour. I was rather proud of myself on this one. The fact that the fig rennet worked like a charm made me feel pleased but also excited to taste the results of this unusual and historically Roman method of cheese-making. Again, it does have a slightly bitter aftertaste but I’ll bet you that it tastes a lot better than if I’d decided to use fresh animal rennet from a rumanant’s stomach! No thank you! Experimental food archaeology wins again!

    Very interesting article! I’m looking for more information on grape leaf wrapped cheese. I did my first one recently and was pleased with the taste ( I wrapped a Belper Knolle or shanklish rolled in herbs de Provence). My leaves were not easy to remove.

  2. Hi Farrell,

    After your Zoom workshop a coupe of weeks ago I’m dead keen to try Columella’s cheese, as I happen to have a fig tree that needs cutting, so will have a lot of fresh fig leaves free to use quite soon! Before I start, I have some questions though:

    – *Very* roughly, how much cheese (in weight or diameter) should I expect to get from a gallon of goat’s milk? I’ve never tried making cheese before so I have literally no idea.

    – Do you put all 3 tablespoons of fig rennet into the milk?

    -Does the fig rennet keep (i.e. is it worth making a bigger batch of it and keeping it in a jar), or do you have to make it from fresh leaves each time? If the latter, then obviously Columella’s method can’t be used for much of the year. (Of course, in his time goats wouldn’t be producing milk during the winter either, but even so there might well not be green sappy bark on the fig trees throughout the milking season.)

  3. Hi Farrell!

    After making Panis Quadratus in your Zoom workshop a week or so ago I’m pining to try making Columella’s cheese, especially as I have a fig tree that needs a bit of cutting back, so I will have plenty of leaves to put to a good use!

    Before I start, please can you tell me:

    – How much cheese, *very* roughly, should I expect to get from a US gallon of goat’s milk? Either an approximate weight or dimension-of-ball would be fine, just to give a first-time cheesemaker a clue.

    – Do you put all the approx-3-tbsps of fig rennet into the milk?

    – Does the fig rennet need to be freshly made? Or can you make it a day or so ahead of time? Or, indeed, can you make up a bigger batch of it and store it?

    I love your site, Sit tibi salutem!

      Hi Victoria! Thanks for attending the Zoom workshop. Experiment with the volumes of output. It will depend on the fat content of the milk. As for the rennet, use it sparingly. It’s bitter and leaves an after-taste. Try a few drops from one cutting and then add more if the milk does not curdle. Don’t put in 3 tbsp of the sap itself. As I said in the post, I actually cut and boiled the stems to extract rennet from the cuttings in a water reduction that I added to the milk. This also worked and curdled it. Post your results on the Facebook page! – Farrell

      • Frank A Ellis-Macera

        Wanted to chime in.
        I just translated a similar cheese recipe I was given.

        A simpler none boiling method in the recipe not for this cheese as you outlined in your post was to simply use a leaf or 2 to stir the milk a few times or no more then 7 drops of fresh fig sap.

        I suspect this was from a few goats that averaged a gallon per goat each day. The cheese was about 6 pounds as I recall. The fat content of the milk being roughly 7.5% fat content. Looking at about 6 gallons of milk I think for the 6 pounds of cheese. Roughly…its late math is not my strong suit.

  4. Paul Arpaia

    I loved reading about fig milk. When my Sicilian nonna used to make cheese, she would trim young fig stems, break them about every inch and put them in the milk as she heated it. (She brought trimmings from her white and black fig plants when she emigrated to the USA in 1931!) She always knew how much fig branch to add. I loved watching her make cheese “magically” as a kid. The cheese was magical, too.

    • Farrell Monaco

      This is a beautiful memory, Paul! Food is often tied to people we love and this is a stunning example of that. – Farrell

  5. Oh oh, after doing everything the rigjt way….it’s still a pot full of milk… what went wrong??

    • Farrell Monaco

      Hi Charlotte! This can happen if you use ultra-pasteurized milk. Sometimes milk that is not raw is also a bit finicky. Try using organic whole milk. Try adding more lemon or fig rennet. Also, heat it to a boil again if it does not separate. This usually solves the problem for me. Let me know if this helps! – Farrell

  6. I am writing this quickly without doing proper research – mea culpa. But I think I found a roman recipe (apicius?) for wrapping the cheese in leaves, or draining it on the leaves, probably bay, or even melissa? I know you can wrap in Chestnut leaves and grape leaves, but some of that is to preserve moisture, not add Flavour?

    • Farrell Monaco

      Hi Mary! Give me some time to look further into this. I have made libum which is a cheese and wheat honey cake that is baked on top of bay leaves. Is this what you’re thinking of? https://tavolamediterranea.com/2017/08/16/libum-catos-cake-bread/

  7. Cindy Tomamichel

    Great article. Instead of using a weight I have hung the cheesecloth ball from a tap to drain. I might try a weight next time, it must change the texture.

    • Farrell Monaco

      Thanks Cindy! Hanging is definitely a great idea. I think the point is to apply some pressure/draw but not too much. Twisting and squeezing it makes some of the curds come out of the cloth membrane. The weight and hanging (gravity) allows the process to move faster but not too fast! 🙂
