Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chestnuts
- Provide the main body and starchy, mashable base of the croquettes.
- Butter
- Adds fat and richness, softening the mixture and improving flavour.
- Egg
- Binds the mixture and, beaten, forms a coating that helps the cracker dust stick.
The step that matters
Fry in deep hot fat until golden brown. If the fat is not hot enough, the coating absorbs oil and turns greasy before it browns. A hot fat sets the crust quickly, keeping the inside moist and the outside crisp.
Swap the chestnut
How well each one fits the dish's main ingredients (pepper, onion, butter, egg):
- Sesamefits better
- Beansfits better
- Black-eyed peafits about as well
- Chestnutthe original
Fit is the average pairing score against pepper, onion, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
