Moretum is an herb cheese spread that the Ancient Romans ate with bread.
[1] A typical moretum was made of herbs, fresh cheese, salt, oil, and vinegar.
A recipe can be found in the poem of the same name in the Appendix Vergiliana.
[2] De re rustica, book XII of Columella contains further recipes for moretum.
The variant with pine nuts is considered to be a precursor of pesto.
