Divide the fish in half: just cut one half into medium-sized pieces, the second as small as possible.
In a separate container, mix the fish (the part that was cut very finely), butter, egg, flour, grated cheese and salt. Knead the dough and put it in the freezer for 10 minutes.
At this time, cut the potatoes into cubes and send them to the rice...
We also add curry there. Cook potatoes and rice until almost ready.
We make balls from the dough, we send them to the second part of our fish in a pot. Cook for 7 minutes on low heat.
