So basically 'headchese' or 'brawn' ?
Never had it made with fish though. Pig, milk piglet, cow, calf. Sulze in my family.
Salmon or Trout in Aspic is a classic dish. 1970's favourite in Sweden and Norway.
Only because they started importing a nasty variety of a Salmon (salmonid) that was cheap but not nice to eat the normal way we eat salmon.
Just the thought of Salmon in Aspic brings out a shudder in me.......
1970's had a lot of shudder value foods. Advocat prawn cocktail, etc.,
Brawn is pig head, hough is from the leg. Head meat (cheek apart) is inclined to be fatty. Hough is more jelly than fat, iimmc ?
