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 stew pan, melt the butter and sauté the minced onion until it simmers.
Add the flour and stir until the mixture is smooth and frothy.
Pour in the milk and season with salt and pepper; let it boil while stirring.
Mix in the chopped meat and mashed potato thoroughly, then spread on a plate to cool.
Shape and coat
Once cool enough, shape the mixture into balls or rolls.
Dip each in the 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
- Cold meat
- Provides the main savoury filling and bulk of the croquette.
- Mashed potato
- Adds body and moisture so the mixture holds together when shaped.
- Flour
- Thickens the milk into a smooth binding sauce that holds the filling together.
- Milk
- Liquid that cooks with the flour into a creamy binder.
- Beaten egg
- Binds the shaped mixture and helps the crumb coating adhere.
- Butter
- Fat that cooks the onion and adds richness to the binding sauce.
The step that matters
Cool the mixture before shaping. A warm, soft mixture is sticky and falls apart when shaped and coated. Cooling lets the starch and flour set so the balls hold their form in the hot fat.
Swap the onion
How well each one fits the dish's main ingredients (butter, flour, milk, pepper, meat, potato, egg):
