Fillet cooked according to this recipe turns out to be incredibly tender, very juicy and fragrant. If you do not take into account the pickling time, then this dish is prepared quite quickly. Very tasty, try it!
Put the chopped fillets in a bowl. Add vegetable oil, soy sauce, salt and spices. Mix it. Cover with cling film and leave to marinate at room temperature for at least 30 minutes. I usually leave it for 1 hour.
Cut the peeled onion not too thinly.
Wash the apple, remove the bones, cut into slices.
Fry the onion on a mixture of butter and vegetable oils until transparent.
Add the marinated meat.
Fry for 5 minutes on high heat, stirring, until the meat is slightly browned.
Then add the apple. Reduce the heat, cover and simmer for 10 minutes.
