Patina de Rosis [Baked Brains & Roses] (Roman, ca. 5th century CE)

img_5800.jpg“Take roses fresh from the flower bed, strip off the leaves, remove the white from the petals and put them in the mortar; pour over some fish sauce and rub fine. Add a glass of fish sauce and strain the juice through the colander. This done, take four cooked calf’s brains, skin them and remove the nerves; crush eight scruples of pepper moistened with the juice and rub with the brains; thereupon break eight eggs, add a glass of wine, a glass of raisin wine and a little oil. Meanwhile grease a pan, place it on the hot ashes or in the hot bath in which pour the above described material; when the mixture is cooked in the double boiler, sprinkle it with ground pepper and serve.”
~ De re coquinaria (Apicius) Book 4, Chapter 2, ca. 5th century CE

I’m a big fan of eating brains.

My Roman ancestors felt the same way. The Roman cookbook Apicius contains recipes for brain sausages, brain-stuffed squash fritters and rose patina (patina de rosis), a baked dish of scrambled brain and eggs, flavored with roses.

Except among zombies and evil meteors, eating brains is far less popular globally than it once was. Modern science has found brains to be very high in cholesterol, and also tarnished their reputation by associating them with a deadly epidemic. That would be mad cow disease, properly known as bovine spongiform encephalopathy (BSE). In the 1990s, a BSE outbreak in the UK caused a global panic, leading to the deaths of over 200 people and the slaughter of 4.4 million potentially-infected cattle.

Caused by the malfunctioning of DNA proteins called prions, BSE results in holes in the victim’s brain tissue (hence the name “spongiform”), leading to neural degeneration and death. It can be contracted from eating the meat and especially the brain of an infected animal, and transmission is unaffected by cooking. Which raises a reasonable question–didn’t the brain-craving Romans suffer from mad cow disease? Not exactly.

BSE is not the only prion disease, and similar livestock illnesses are described by ancient writers such as Hippocrates in 400 BCE and Vegetius, who lived at the same time when Apicius was composed (4th and 5th centuries CE). But most prion diseases cannot pass from animal to human, making mad cow disturbingly unique. There is no ancient account of a person contracting a prion disease, although Hippocrates mistakenly conflated prion disease in animals with epilepsy in humans because of their similar symptoms.

BSE was first identified in 1986, and its development and spread were directly linked to the industrialization of 20th-century farming. Undesirable bits from slaughtered cattle, including their brains, were ground up and fed to living cattle as a protein supplement called MBM or “meat and bone meal”, inadvertently infecting the animals with prion disease (and giving me grisly flashbacks to Soylent Green and the “soap” from Cloud Atlas). Because of the ’90s BSE outbreak, most countries have banned the use of MBM in feed for ruminant (cud-chewing) animals such as cows and sheep, although it is still an ingredient in commercial pet food.  As a further precaution, since prion diseases do not manifest until adulthood, it is now illegal in many countries to sell brain from an adult cow. Which is to say that this recipe, which uses calf brains, is just about as safe as it was in Roman times.


The sweet wine in the original Roman recipe, called passum, was made from raisins, making it a type of straw wine. Passum is still made in Italy today under the slightly-different name of passito. You can also use marsala, sherry, or Manischewitz.


The main ingredient, looking exactly how you would expect.

Apicius provides some unusually specific instructions about incorporating roses into this dish: take fresh roses, “cut off the white” (presumably separate the petals from the flowerheads), grind with fish sauce and strain. I attempted this with fresh roses and their flavor/scent did not carry over into the fish sauce, so I ended up using rosewater (or rose tea), which I made by soaking dried rose petals in hot water.

-2 calf’s or pig’s brains (available, fresh or frozen, from halal butchers and some Mexican or Asian grocery stores)
-4 beaten eggs
-1/3 cup rosewater
-1/3 cup fish sauce
-1/2 cup sweet cooking wine
-1 teaspoon black pepper
-rose petals for serving (optional)

Rinse the brains in cold water and pat dry. Bring a small pot of water to a boil, lower the heat and simmer the brains until they are gray and a fork can pierce them easily (about 10 minutes).

In a blender or food processor, combine brains with all the other ingredients and blend until smooth. Pour the liquid into a pie dish greased with olive oil.

Apicius instructs the chef to cook the dish by placing it in termospodio, “in the embers.” You can use a double boiler to replicate the even, gentle heat of hot coals. I balanced my 9-inch pie dish on top of a cast-iron pan filled with water and added a lid.

Cook the patina over low heat for 40-45 minutes, until a fork inserted in the center comes out clean.

Serve with rose petals and more black pepper.


The flavor of brain resembles liver mousse, rich and creamy. The roses are an interesting addition, with a subtle flavor balanced by the sweetness of the wine. Like many baked Roman patinae, this one is soft and wet enough to require a spoon. Eat it by itself or with bread, while it’s still hot (nobody likes cold brains).


Ancient Recipe: Asparagus Patina (Roman, 4th century CE)

Asparagus patina is made like thisPut in the mortar asparagus tips. Crush pepper, lovage, green coriander [cilantro], savory and onions; crush, dilute with wine, liquamen [fish sauce] and oil. Put this in a well-greased pan, and, if you want, add while on the fire some beaten eggs to thicken it, cook without boiling the eggs and sprinkle with very fine pepper. ~ De Re Coquinaria (On Things Culinary) or Apicius, Book II

patina cooked

Originally, a patina was a specific type of Roman pottery; a round, flat, shallow dish. Over time, the word came to be used for the food cooked in the dish, not just the dish itself (compare modern terms like barbecue, hot pot, and terrine). The 4th-century Roman cookbook Apicius has a whole chapter devoted to patina recipes, including patinae of vegetables, fruits, meat, fish, and my personal favorite, calf’s brains and roses. The only common ingredient is ovae, eggs. As such, modern authors have often characterized patina as similar to a modern frittata, raw beaten eggs mixed with other ingredients and baked until solid. But the recipes in Apicius use eight different verbs to describe methods of incorporating eggs into patina, implying that the term was a general one covering everything from baked scrambles to delicate, airy soufflés. There were also egg-free variations, as in the recipe above, which instructs you to add beaten eggs only si volueris, “if you want”.

An element of surprise or trickery is found in many Roman dishes, making the food itself a form of table-side entertainment as guests attempt to identify what’s front of them. This celebration of the transformative aspects of cooking is found in many cultures, from Medieval European sugar-sculpted “subtleties” to the old Korean tradition of reshaping fruits and nuts into a confection shaped like the original. With its brilliant green color and the unusual step of pureeing the asparagus, I can imagine a group of Roman diners being similarly charmed and surprised by this recipe. I’ve made it for an Ancient Roman dinner I hosted and for my classes on Roman food, and it holds up to a modern taste-test quite well. It is named in the text of Apicius as “aliter patina de asparagis“, “another asparagus patina“, because there is a similar recipe immediately preceding it. The first asparagus patina is almost identical except for one ingredient: the meat of tiny birds called ficedulae (literally “fig-peckers”), three of them for one patina. I’ll be saving that for another time.


As it doesn’t deviate far from the modern palate, this is one of the most popular Ancient Roman recipes for revival, and there are numerous modernized versions out there. I mainly follow Cathy Kaufman’s reconstruction in her book Cooking in Ancient Civilizations (2006), but this recipe can also be found in other great books about Roman cooking, like A Taste of Ancient Rome (1994) and The Classical Cookbook (2012). The original Latin says to strain the crushed vegetable and wine mixture, a step which some translators follow and others, like the one quoted above, don’t. I personally think the recipe is better if you don’t strain. Roman vegetables were tougher and stringier than our vegetables, so this step was probably necessary to make 4th-century asparagus more palatable, but most modern asparagus will turn out sufficiently soft anyway.

Modern fermented fish sauce (available where Asian groceries are sold) will stand in for the near-identical Roman version. Savory and lovage are two herbs used in this recipe that you might not be familiar with, as they are less-popular today than they were in historical times. Savory is one of the traditional components of herbes de Provence and has a slightly bitter, spicy flavor. If you can’t find it, use thyme, marjoram or sage. Lovage has a similar flavor to celery, and crushed celery seed or the inner leaves of celery make a good substitute. All these substitutions were plants known to the Romans, so perhaps a strapped 4th-century chef might have done the same. The presence of pepper in the recipe hints at the intended audience of Apicius: enslaved or formerly-enslaved career chefs laboring in the kitchens of the wealthy. In Rome, pepper (known in three forms, black, white, and long) was a costly dried import from India. Households of more limited means used only fresh green herbs as seasoning.

Asparagus and herb mixture.

First, gather your non-liquid ingredients: six eggs, 1 bunch of asparagus (trimmed), 1/4 cup chopped onion, 1/4 cup cilantro leaves, 1/4 teaspoon ground black or long pepper, 1 teaspoon dried savory or sage, and 1/8 teaspoon celery seed or lovage.

You will also need 1 tablespoon of olive oil (plus more for the dish), 1/2 a cup of white wine, and 1 tablespoon of fish sauce.

Preheat the oven to 400 °F. Spread the inside of a one-quart gratin dish, pie dish, or cast-iron skillet with oil.

Puree all the ingredients except the eggs in a food processor or a mortar and pestle. Depending on the size of the equipment you are using, you may find it necessary to mash up the asparagus first and then add it to the other ingredients. Make sure everything is combined to a smooth, even texture. Beat the six eggs and add them to the pureed vegetables. Mix well to combine, and pour the mixture into the dish. Bake until set (about 35-40 minutes. If a fork or chopstick inserted into the center comes out clean, the patina is done). Serve with fresh cracked pepper.

The predominant flavor in this dish is, of course, asparagus, but the spices and herbs come through quite nicely. It’s best-served and eaten with a spoon, as it has a mushy texture. It goes well with crusty bread, white wine, and, I’m assuming, fig-peckers. VIII out of X.
