First, cut the onion and fry it until golden brown. Squeeze out of our citruses 100 ml of orange and 50 ml of lemon juice. Add juice, tomatoes and all the spices to the onion, chop the garlic, mix. Stew over low heat for 20 minutes, stirring occasionally. We try the sauce, if it is very sour, add sugar to taste. Add salt and pepper to the fish and put it on a greased baking sheet. Put our sauce on top. We send it to the oven for 20-20 minutes for 20-20 degrees.
