Mackerel cream

There is a stall in La Rochelle market where one can buy not only fresh, smoked, or boiled fish and seafood but also different kinds of salad and cream all made with fish, obviously. While spending our vacation there, we tried different products from their stall, mackerel cream being one of them. A pretty staple food in France, as there is a big love for mackerel in this country. Mostly, though, the French love smoked mackerel, and, if you cannot get fresh fish, do use smoked, omitting the cooking part.
