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
Melt the butter in a stew-pan 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 continuously.
Mix in the chopped meat and mashed potato thoroughly, then spread the mixture on a plate to cool.
Shape and coat
Once cool, shape the mixture into balls or rolls.
Dip each ball in beaten egg, then roll in cracker or bread crumbs.
Fry and serve
Fry the coated balls in hot lard for about two minutes until golden brown.
Remove the croquettes with a skimmer and drain on brown paper.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the flavour and helps form the base of the white sauce.
- Flour
- Thickens the milk into a smooth binding sauce that holds the mixture together.
- Milk
- Forms the liquid of the sauce, adding moisture and creaminess to the filling.
- Mashed potato
- Adds body and moisture, helping the filling bind and stay tender.
- Egg
- Binds the coating so the crumbs adhere and set during frying.
The step that matters
Cooling the mixture before shaping. If the filling is still warm, it stays soft and sticky and will not hold its shape. Spreading it to cool lets the starch and sauce firm up, so the balls keep their form and do not break apart in the hot lard.
