by Apicius I, XXXV
Not much to say really... there a LOT of sauces in Roman cooking and it is kind of frustrating to nail things down. This appears to have continued a lot in British cooking.
Original recipe: Mentam , rutam, coriandrum, feniculum, omnia uiridia, ligusticum, piper, mel, liquamen. Si opus fuerit, acetum addes.
Translation: Mortaria are preparations made in the mortar. Place in the mortar: mint, rue, coriander and fennel, taking care that these herbs are fresh. (...all fresh and green and crush them fine). Add lovage, pepper, honey and broth and stock. If there is a need, add vinegar.
