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.
Pour in the milk and season with salt and pepper; bring to a boil while stirring.
Mix in the chopped meat and mashed potato until well combined.
Spread the mixture on a plate to cool.
Shape and coat
Once cool, shape into balls or rolls.
Dip each in beaten egg, then roll in cracker or bread crumbs.
Fry and serve
Fry in hot lard for about 2 minutes until golden brown.
Remove with a skimmer and drain on brown paper.
Serve immediately while hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms a roux with the butter that thickens the milk into a smooth binding sauce.
- Milk
- Liquid that, with the flour, makes a thick sauce that holds the mixture together.
- Mashed potato
- Adds body and moisture, helping the mixture bind and stay tender inside.
- Cold meat
- Provides the savory filling that the binding sauce holds together.
- Beaten egg
- Coats the shaped croquettes so the crumbs adhere and form a crisp shell.
- Cracker or bread crumbs
- Form a crisp, browned outer crust when fried.
The step that matters
Cooling the mixture before shaping. If the mixture is still warm, it is soft and sticky and will not hold its shape or stay intact in the hot fat. Cooling firms the starch-thickened binder so the croquettes 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):
