Name: Rice and Nut Croquettes
Ingredients: 2 tablespoons butter; 2 tablespoons flour; 1 cup milk; 2 cups cooked rice; 1 cup chopped peanuts or bleached almonds; onion juice to taste; lemon juice to taste; coarse sea salt to taste; cayenne pepper to taste

Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

Rice and Nut Croquettes

Ingredients

Directions

Make the sauce

Make a white sauce by melting the butter in a saucepan, then whisk in the flour until smooth.
Gradually add the milk, stirring constantly until the sauce thickens.

Assemble and cook

Mix in the cooked rice and chopped peanuts or almonds.
Season with onion juice, lemon juice, coarse sea salt, and cayenne pepper.
Shape the mixture into croquettes and fry them until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Butter: Enriches the white sauce and adds richness and flavor to the croquettes.
Flour: Thickens the butter and milk into a white sauce that binds the rice.
Milk: Forms the liquid base of the white sauce, giving it body and creaminess.
Cooked rice: Forms the bulk of the croquettes and gives them their tender interior.
Peanuts or almonds: Add crunch and nutty flavor to the soft rice mixture.

The step that matters

Frying the croquettes until golden brown. Frying browns the outside through the Maillard reaction, creating a crisp shell while the starchy interior stays soft. Too little heat leaves them greasy, and too much burns the outside before the centre is hot.
