- Start by soaking the cashews in room temperature water for at least 1 hour, 2-3 hours if possible. Add the nuts to a blender or food processor along with the other sauce ingredients. Process until smooth. If you want a thinner texture, add a little water.
- In a large frying pan, fry the onions in half of the butter over medium heat for 3 minutes until they begin to soften. Add tomatoes and a little salt and pepper to taste. Fry until the tomatoes begin to soften.
- Stir in the finely chopped cilantro or any other fresh or dried herbs. Set aside in a bowl or a plate, covered to keep warm.
- Wipe the fish dry. Mix together the spices and season the fish. In the same pan, fry the fish in the remaining butter or oil over medium heat for a few minutes on each side until the fish flakes easily with a fork or reaches about 120° F (50° C) internal temperature.
You can use any type of white fish or even salmon. For a completely dairy-free meal, use olive oil for frying.
