Silphium

Here is a recipe, taken from the Roman gourmand Apicius:

Oxygarum (which is similar to garum or rather an acid sauce) is digestible and is composed of:

• 1/2 ounce of pepper
• 3 scruples of Gallic silphium
• 6 scruples of cardamom
• 6 of cumin, 1 scruple of leaves
• 6 scruples of dry mint.

These ingredients are broken singly and crushed and made into a paste bound by honey. When this work is done or whenever you desire add broth and vinegar to taste.
