Libum (Ancient Roman Cheese Flatbread)
Libum is one of the oldest written recipes in Western culinary history. Recorded by Marcus Porcius Cato the Elder in De Agri Cultura around 160 BCE, this ancient Roman cheese flatbread requires three ingredients and has not changed in over two thousand years. A ritual offering to the household gods — lares and penates — it was also everyday food for Roman commoners. The recipe belongs to the ancient cuisine of Rome that anyone can recreate at home without adaptation. Relevant for anyone interested in ancient recipes, paleo diet history, Roman culinary tradition, and ancestral cooking. Served hot with honey, it transforms from a neutral dense cake into something that tastes unmistakably of antiquity.
Ingredients
- 600 gfresh unsalted ricotta
- 150 gspelt or wheat flour
- 1 egg
- 8 fresh bay leaves
- 4 tbsphoney for serving
- 1 tbspolive oil for the pan
Method
- Drain the ricotta. If the ricotta is wet, place it in a fine-mesh sieve or wrap in cheesecloth and leave over a bowl for 30 to 60 minutes. Excess moisture makes the dough too soft to hold its shape. The ricotta should be firm enough to hold a spoon impression. This step is the most important preparation in the recipe.
- Work the cheese. Transfer the drained ricotta to a deep bowl or stone mortar. Following Cato's instruction — 'bray well in a mortar' — work the cheese with a pestle or the back of a wooden spoon until it becomes a completely smooth, plastic mass with no lumps. This takes 2 to 3 minutes. The cheese must be uniform before any flour is added.
- Make the dough. Add the spelt or wheat flour to the cheese gradually, working it in with your hands. Add the egg. Knead for 3 to 4 minutes until a cohesive, slightly sticky dough forms. The dough will be denser than bread dough and noticeably wetter. Do not add more flour to compensate: the high cheese-to-flour ratio — two parts cheese to one part flour, as Cato specifies — is what makes libum what it is. A drier dough produces bread, not libum.
- Shape. Lightly flour your hands. Turn the dough out and shape into a flat round disc approximately 14 cm in diameter and 2.5 to 3 cm thick. Libum is a flat sacrificial cake, not a loaf. Keep it low and even.
- Prepare and bake. Preheat the oven to 200 C. Lightly oil a baking dish or cast-iron pan with olive oil. Arrange the fresh bay leaves on the bottom — they will perfume the underside of the cake as it bakes. Place the libum on the leaves. Bake for 30 to 35 minutes until the surface is deep golden-brown and firm to the touch. The underside should carry the faint imprint of the leaves.
- Serve with honey. Warm the honey in a small pan or microwave until fully liquid. Remove the libum from the oven and immediately pour the warm honey over the hot surface. The hot cake absorbs honey more deeply than a cooled one. Remove and discard the bay leaves before serving. Cut into wedges and serve at once. Libum is at its best in the first 10 minutes after baking.

Oven thermometers don't lie — your oven dial probably does. I discovered my oven runs 15°C hot, which explained years of slightly overbaked results. For libum, the actual 220°C matters more than the dial position.
