Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salmon
- Provides the main body and flavor of the croquettes.
- Milk
- Forms a thickened binding base that keeps the mixture moist.
- Flour
- Thickens the milk so the mixture holds its shape.
- Egg
- Binds the mixture and, as a coating, helps crumbs adhere and brown.
- Butter
- Adds richness and moisture to the mixture.
- Bread crumbs
- Form a crisp, golden outer crust when fried.
The step that matters
Fry the patties in hot oil until golden brown. If the oil is not hot enough, the crumb coating absorbs oil and turns greasy instead of crisp. Hot oil seals the crust quickly, and the patties need to be firm enough to hold together during frying.
Swap the walnut
How well each one fits the dish's main ingredients (salmon, milk, flour, butter, egg, pepper, bread):
- Peasfits about as well
- Almondfits about as well
- Walnutthe original
- Chestnutfits about as well
Fit is the average pairing score against salmon, milk, flour, butter, egg, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
