Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Croquettes of Peas
Ingredients
Directions
Make the base
In a saucepan, combine flour and butter, rubbing them together until smooth.
Gradually add the heated milk, stirring until thickened.
Season with pepper and coarse sea salt, then mix in the canned peas.
Spread the mixture on a platter to cool until firm.
Shape and fry
Once firm, shape into cylinder-shaped croquettes.
Roll each croquette in fine bread crumbs, then dip in the beaten egg, and roll again in crumbs.
Fry the croquettes in hot fat until golden brown.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the milk into a smooth white sauce that holds the peas together.
- Butter
- Adds fat and richness, and combines with flour to form the thickening roux.
- Milk
- Forms the liquid base that thickens into a binding sauce.
- Canned peas
- Provide the main flavor and bulk of the croquette filling.
- Beaten egg
- Binds the breadcrumb coating and helps it stick during frying.
The step that matters
Cooling the mixture until firm. The filling must set fully before shaping, because a warm or loose mixture will not hold its cylinder shape and may burst or spread in the hot fat.
Swap the peas
How well each one fits the dish's main ingredients (flour, butter, milk, pepper, bread, egg):
- Almondfits better
- Chestnutfits about as well
- Walnutfits about as well
- Peasthe original
Fit is the average pairing score against flour, butter, milk, pepper, bread, egg. Candidates are from the same food group and used in at least 100 recipes.
