Libum was a sacrificial cake offered to the household spirits, but the Romans ate it as well!
The following recipe is from the book De Agri Cultura by Cato, who was a consul, statesman, and soldier. I'm sure he got the recipe from his cook.
1/2 cup plain all-purpose flour
1 cup ricotta cheese
1 egg, beaten
1/2 cup clear honey
Sift the flour in a mixing bowl.
Beat the cheese until soft, stir into the flour.
Add the beaten egg to the flour/cheese mixture, forming a soft dough.
Divide the dough into four and shape each piece into a bun.
Place on a greased baking tray with a fresh bay leaf underneath.
Heat the oven to 375F/190C. Bake for 35-40 minutes until golden brown.
Warm the honey, pour into a flat plate, and place the buns on it to rest until the honey is absorbed.
