Why it works: Potato and pepper are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 8,305 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ingredients
Directions
Prepare
Boil the potatoes until tender, then mash them finely.
Mix in the chopped hard-boiled eggs, salt, pepper, and milk or cream.
Shape and fry
Form the mixture into small cakes and dust both sides with flour.
Heat oil in a pan and fry the cakes until they are a delicate brown.

Milk and flour barely smell alike, yet cooks put them together in 78,219 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
- Potatoes
- Form the bulk of the cakes and hold them together when mashed smooth.
- Hard-boiled eggs
- Add richness and body to the mashed potato mixture.
- Milk or cream
- Adds moisture and softness to the mashed potato mixture.
- Flour
- Dusting helps the cakes form a light crust that browns when fried.
The step that matters
Frying the cakes. Oil must be hot enough before the cakes go in, otherwise they absorb excess oil and turn greasy. Flour-dusted surfaces brown quickly, so moderate heat keeps them golden rather than scorched.
Swap the potato
How well each one fits the dish's main ingredients (egg, pepper, milk, flour):
- Capsicumfits better
- Asparagusfits about as well
- Spinachfits about as well
- Potatothe original
Fit is the average pairing score against egg, pepper, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
