Why it works: Potato and onion 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 ↓

makes twelve croquettesIngredients
Directions
Make the potato mixture
Beat the yolks until light.
Add the yolks to the mashed potatoes, cream, grated onion, parsley, butter the size of a walnut, salt, and cayenne pepper. Mix.
Turn the mixture into a small saucepan and stir over the fire until the mixture leaves the side of the pan.
Take from the fire, cool, and form into croquettes.
Coat and fry
Roll first in egg, then in bread crumbs, and fry in boiling fat in a basket. This makes twelve croquettes.
Make the white sauce
Melt 2 even tablespoonfuls butter in a saucepan. Add pepper and salt, then add 4 heaping tablespoonfuls flour. Stir until smooth.
Add gradually heated milk or cream, stirring until smooth.
Melt 2 tablespoonfuls butter in a sauce pan. Add 2 tablespoonfuls flour, 1 teaspoon paprika, and 34 teaspoonful salt. Blend thoroughly.
Add 1 cup milk a little at a time, stirring until smooth, and cook until thick, stirring slowly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mashed potatoes
- Form the bulk of the croquette and set firm when cooled and shaped.
- Eggs
- Bind the mixture and help the coating adhere for a crisp shell.
- Flour
- Thickens the milk into a smooth sauce that holds the mixture together.
- Milk
- Forms the liquid base of the sauce, thickening as the starch cooks.
- Butter
- Adds richness and flavour and helps make the roux smooth.
The step that matters
Stir the potato mixture over the fire until it leaves the side of the pan. Drying the mixture well lets it cool firm enough to shape without sticking or falling apart in the hot fat.
Swap the onion
