Libum

Libum was a cake prepared in antiquity that was closely associated with honey.^[1] Besides referencing a specific cake, libum came to be used as a name for cakes in general.^{[2] [3]}

When referenced as a specific cake, libum appears to have been the most common offering of all Roman cakes.^[2] The use of cakes as sacrifices was not new to Roman society—they had been used for such purposes since at least the time of the Greeks.^[2] Ovid gives a description of the cake in such a context, describing the cake as an offering to Vesta, the goddess of the hearth,^[2] and traces the origin of the cake to the discovery of honey by Bacchus, the god of wine.^[1] The name itself references the role in sacrifices, deriving from the Latin libare, "to offer to the gods", and is first referenced in the poem Annales, written by Ennius.^{[4] [1]}

With sugar not yet available to Roman society and butter considered only suitable as a healing balm, honey was used as the basic sweetener and cheese was used as a source of fat.^[5] The two in combination was typical among desserts, as also seen in the more complex placenta cake.^[6]

Preparations varied—the version described by Ovid contained millet, while the version referenced by Athenaeus contained itriya, a shaped, proto-pasta made from wheat flour.^[7] The resulting cake could be served in a range of contexts: more hearty versions at home, and more delicate preparations at the end of formal dinners.^[1]

While libum is referenced by various Roman poets, the only recipe given in antiquity for libum is given by Cato the Elder, in his treatise De agri cultura that he wrote circa 160 BCE.^{[8] [1]} Cato presents a basic dish that combined flour and cheese curds.^[9]

Cato cooked his libum on bay leaves.^{[1] [10]} These, writes Ernestine Leon, flavored the cake as it cooked, and would have served the same role as modern parchment paper. For the latter role to work, Leon infers the leaves "must have been" dry as wet leaves would have stuck to the baked cake.^[10] Baking the cake using feta and modern kitchen equipment, Andrew Dalby and Sally Grainger report Cato's recipe makes a "delicious savoury cheesecake" with a "golden-brown crust and soft centre".^[1] Likewise, Leon reports the resulting cake is "palatable", and notes that while the amount of cheese may seem "excessive", its ratio to other ingredients is close to that of shortening and flour in the modern shortbread.^[10] The lack of honey in Cato's recipe was unique among ancient references to the cake; and Dalby and Grainger suggest inclusion may have been implied. Such a recipe modified to include honey, they advise the modern cook, would be more appetising made with a less salty cheese like ricotta.^[1]

It is unclear why Cato presented a recipe for cake recipes in a text on agriculture: theories include that it could offer some farmers an extra source of income, or that they were included for their role in religious rituals.^[2]
