Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold boiled white fish
- Forms the body of the cake and gives it its flaked, tender texture.
- Egg whites
- Bind the fish together so the cake holds its shape when fried.
- Grated bread crumbs
- Absorb moisture and help the mixture hold together as a cake.
- Melted butter
- Adds richness and helps the outside brown when fried.
- Flour and water
- Thicken the stock into a sauce that coats the cake.
The step that matters
Frying the cake on both sides until golden brown. The cake is held together only by bread crumbs and egg white, so it can break apart if handled roughly or turned too early. Letting a firm crust form before turning helps it hold its shape, and browning adds flavour.
