My mackerel, remove the head, innards, cut into 2 halves along the ridge extracted all the bones and the bones on the skin of the head. With scissors cut away all the fins, the ridge. The skin not removed. RUB the salt.

Form grease with oil, turn rolls ("predmostie" inside). Put down the seam. Mackerel is a meaty fish, and the rolls turn out very "specific". Sprinkle with dill (I used salted). Dill you can put more, it is still not much felt, but it is absolutely necessary (it gives dishes a unique taste).

Dilute tomato paste with water. Fill the fish. And put in a preheated 180 - 200 degree oven for 30 minutes. Get tight and enjoy the fish rolls with potatoes.
