Why it works: Onion and potato are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Meat and Potato Croquettes
Ingredients
Directions
Make the base
In a saucepan, melt the butter and sauté the minced onion until it simmers.
Add the flour and stir until smooth and frothy.
Gradually add the milk, stirring continuously until it boils.
Shape and coat
Mix in the chopped cold meat and hot mashed potato thoroughly, then cool on a plate.
Shape the mixture into cones or rolls.
Dip each piece in the beaten egg, then coat with cracker crumbs.
Fry and serve
Fry in boiling oil until golden brown, then drain on paper and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold meat
- Provides the savory bulk and flavor that forms the body of the croquette.
- Mashed potato
- Adds body and softness, helping the mixture hold together when shaped.
- Flour
- Thickens the milk into a sauce that binds the meat and potato together.
- Milk
- Makes the flour-based sauce creamy, adding moisture to the mixture.
- Beaten egg
- Binds the shaped pieces and helps the cracker crumbs adhere as a coating.
- Cracker crumbs
- Form a crisp, golden coating that browns during frying.
The step that matters
Cool the mixture before shaping. If the mixture is still hot and loose, it will not hold its shape and may split or slump in the oil. Cooling it firms the starch and fat so the cones or rolls keep their form while frying.
Swap the onion
How well each one fits the dish's main ingredients (butter, flour, milk, pepper, meat, potato, egg):
