Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the cakes and provides their savoury flavour.
- Potatoes
- Add starch and bulk, helping the mixture hold its shape and stay moist.
- Egg yolks
- Bind the mixture together and add richness to the cakes.
- Butter
- Adds richness and moisture, and helps the cakes brown in the pan.
- Lard
- Fat for frying that conducts heat evenly and promotes a golden crust.
The step that matters
Forming and frying the cakes. The mixture is soft and wet, so it needs to be shaped firmly and kept cool enough to hold its form. Frying in hot fat sets the outside quickly into a crust, helping the cakes keep their shape and turn golden brown.
Swap the mustard
