Marinated Fish in Mustard Sauce (Poisson Yassa)

Poisson Yassa is a spicy dish prepared with onions and marinated poultry (poulet) or fish (poisson). Originally from Senegal, yassa has become popular throughout West Africa. Another even more important gift from the region is the “preserver of African traditions”, the Griot.

Africa has a strong, deep, and rich oral tradition. In many countries across West Africa, this tradition is often preserved by the griots (gree-ohs), who are historians, storytellers, poets, and musicians. Often, the griot is the preserver of the history of a family, clan, and sometimes of the whole nation. This is done by narrating how the family/clan/tribe/nation was founded and its outstanding achievements. In essence, the griot is a repository of the oral tradition.

The West African griot … knows everything that is going on… He is a living archive of the people’s traditions… The virtuoso talents of the griots command universal admiration. This virtuosity is the culmination of long years of study and hard work under the tuition of a teacher who is often a father or uncle. The profession is by no means a male prerogative. There are many women griots whose talents as singers and musicians are equally remarkable.”

To this day, mostly through song, griots carry this important responsibility from one generation to the next so that the stories and lessons of the past will never be forgotten. It’s not clear if part of their responsibilities consist of handing this simple-yet-delicious fish dish to the next generation. If not, it should be.

Poisson Yassa – Senegalese Fish in Mustard Sauce

This French influenced dish showcases citrus marinated fresh fish that is contrasted by a smooth mustard sauce. In Senegal, whole fresh red snapper is used. Any firm white fish filet like tilapia, sea bass, or salmon will work equally well.
