Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide starch and bulk, giving the cakes a soft, mashable body.
- Fish
- Supplies the main flavour and protein that gives the cakes their substance.
- Egg yolk
- Binds the mixture so the cakes hold their shape when cooked.
- Whole egg
- Forms a coating that helps bread crumbs adhere and brown during frying.
- Butter
- Adds richness and fat, contributing flavour and a tender texture.
- Bread crumbs
- Form a crisp, golden crust when the cakes are fried.
The step that matters
Let the mixture cool before shaping. A warm, soft mixture is sticky and hard to shape. Cooling firms the starches and fats so the cakes hold their form and do not break apart in the hot fat.
Swap the potato
How well each one fits the dish's main ingredients (fish, butter, milk, egg, bread, pepper):
- Capsicumfits about as well
- Potatothe original
- Asparagusfits about as well
- Tomatofits less well
Fit is the average pairing score against fish, butter, milk, egg, bread, pepper. Candidates are from the same food group and used in at least 100 recipes.
