Why it works: Pepper and onion are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Pea Croquettes
Ingredients
Directions
Make the paste
Pour the peas into a basin and heat to boiling point.
Rub the peas through a sieve to create a smooth pulp.
Stir in the butter and flour until combined.
Season with pepper, salt, and onion juice.
Add the beaten egg and cook in a double boiler until a stiff paste forms.
Shape and fry
Shape the mixture into high cones.
Dip each cone in egg and roll in breadcrumbs.
Fry in deep oil until golden brown.

Butter and flour 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
- Peas
- Form the main body of the croquettes, becoming a smooth pulp that sets into a firm paste.
- Flour
- Thickens the pea pulp so it holds its shape when shaped and fried.
- Egg
- Binds the mixture so it sets into a stiff paste and helps the breadcrumbs adhere.
- Butter
- Adds richness and a softer texture to the paste.
- Breadcrumbs
- Form a crisp, golden outer coating during frying.
The step that matters
Cooking the paste to a stiff consistency. The mixture must thicken fully in the double boiler before shaping. Undercooked paste stays soft, so the cones slump and can break apart in the hot oil. Gentle heat also keeps the egg from scrambling.
Swap the peas
How well each one fits the dish's main ingredients (butter, flour, pepper, onion, egg):
- Almondfits better
- Black-eyed peafits better
- Sesamefits better
- Peasthe original
Fit is the average pairing score against butter, flour, pepper, onion, egg. Candidates are from the same food group and used in at least 100 recipes.
