This recipe makes enough sauce for 4-6 people. It isn't easy to make the sauce in very small quantities, so it would be worth making this amount even if you prepare less meat.
This Roman sauce is a little like a satay. It is quite delicious and has a very intense flavour.
The recipe is from Apicius and has many features common to the cooking of this period. Black pepper and fish sauce are both used for example.
Romans ate reclining and food was generally served to be eaten with your fingers. The meat is cut into strips so it can be dipped and then put straight into your mouth. The sauce needs to be thick enough to cling to the meat, without being too messy.
