Spit Roasted Trouts with Green Sauce – Medieval Recipe

Today we prepare a medieval green sauce with spit-roasted trouts. We selected this recipe from the Opusculum de Saporibus (The Book of Sauces), an interesting source written in Latin about how to make healthy (according to the medical habits of the period) and tasty sauces. The author is a Milanese physician, Maino de' Mainieri, who worked at Visconti's court in the middle of the 14th century.
