I use ground fish from the fish store. You can use whiting, white fish, haddock, carp or lesht or any fish that you might like, and use all the fish ground together. I put a smallish onion in the food processor, with the knife and chop up the onion with a peeled carrot and then I add an egg to make it all liquidy. I then transfer from the food processor this mixture to the Kenwood or Kitchen Aid. Add the minced fish, add another raw egg for a 1 lb of fish. ( I use 2 eggs for every 1 lb of minced fish). Add as much sugar ( I make the fish sweet, salt and pepper, add one plastic cup (approx. 6 oz) of ground almonds for every 1 lb of fish. Put on the mixer and beat with the K beater for at least 20 minutes on high (Kenwood). This gets very fluffy and it makes alot of mixture. Cut large sheets of Bakewell paper and spray the paper with Pam spray. Put mixture on the paper and shape into a roll.
Put the roll into the freezer and let it get hard, then put into freezer bag and seal properly. When needed, boil water with sugar, onion, carrots, salt, pepper, a drop of oil, any bones you might have of fish that you have saved in freezer. Bring to a rolling boil, then add fish roll, bring back to a boil, then simmer on low heat, for about an hour or even more if needed. Keep turning the fish roll over in the boiling water, as it is cooking. Then shut the fire. Remove from pan and place into container. Strain the fish sauce and pour over the fish and refrigerate with the carrots. Slice thickly and serve with chrane and / or mayonaisse. Enjoy!
