Ancient Roman Libum Recipe
Libum to be made as follows: 2 pounds cheese well crushed in a mortar; when it is well crushed, add in 1 pound bread-wheat flour or, if you want it to be lighter, just 1/2 a pound, to be mixed with the cheese. Add one egg and mix all together well. Make a loaf of this, with the leaves under it, and cook slowly in a hot fire under a brick.

Modern Roman Libum Recipe (serves 4)
1 cup plain, all purpose flour
8 ounces ricotta cheese
1 egg, beaten
bay leaves
1/2 cup clear honey

Sift the flour into a bowl. Beat the cheese until it's soft and stir it into the flour along with the egg. Form a soft dough and divide into 4. Mold each one into a bun and place them on a greased baking tray with a fresh bay leaf underneath. Heat the oven to 425° F. Cover the cakes with your brick^* and bake for 35-40 minutes until golden-brown. Warm the honey and place the warm cakes in it so that they absorb it. Allow to stand 30 minutes before serving.

^*The Romans often covered their food while it was cooking with a domed earthenware cover called a testo. You can use an overturned, shallow clay pot, a metal bowl, or casserole dish as a brick.
