Fish patties (Russian specialty)

Cut the fish into tiny pieces. You can also put it through a meat grinder or pulse it in a food processor, but be careful not to turn it into complete mush. Make sure the fish still has some texture to it. You can use just about any fish that you like. For this recipe, I like to use white fish and cod is one of my favorites.
Pour the milk over the toasted bread, and allow it to soak into the bread and soften for a few minutes. Italian bread is very light and airy. If you're using plain white store bought sandwich bread, use only 1 slice of bread, since it's much more dense and will become somewhat gummy as it soaks in the milk.
Puree the soaked bread in the food processor or mash it with a fork.
Mince the celery and the onion. Heat the butter or oil in a skillet, add the onion and celery, season with salt and pepper and saute them in the skillet for 5-7 minutes, until softened.
Add the celery, onion, pureed bread and milk, egg, salt, pepper, mustard and herbs to the fish. Mix to combine.
Place the flour in a shallow bowl.
Form small patties from the fish mixture, dredge them in the flour and set aside. Heat oil in a nonstick skillet until really hot. Cook the patties until golden on both sides, about 4 minutes per side.
