Why it works: Pepper and celery match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 16,012 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Croquettes of French Peas
Ingredients
Directions
Make the base
Melt the butter in a saucepan over medium heat.
Stir in the flour and cook for a minute.
Gradually add the cream, stirring constantly until smooth.
Season with salt, pepper, celery salt, and onion juice.
Form and cool
Mix in the well-beaten egg yolk and the pureed peas.
Pour the mixture onto a platter and let it cool.
Once cooled, shape into croquettes.
Fry
Fry the croquettes in hot 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
- Butter
- Enriches the base and adds richness and flavour as it melts into the sauce.
- Flour
- Thickens the butter and cream into a smooth, sliceable base that holds the croquette shape.
- Cream
- Provides moisture and richness that, with the flour, sets into a thick, creamy binder.
- Egg yolk
- Binds the mixture and helps it set firm enough to shape and fry.
- Peas
- Supply the main flavour and bulk, with their starch helping thicken the mixture.
The step that matters
Gradually add the cream while stirring constantly. Adding cream slowly while stirring keeps the flour evenly dispersed, so the sauce thickens smoothly without lumps. Lumps would make the base hard to shape and fry evenly.
Swap the peas
How well each one fits the dish's main ingredients (butter, flour, cream, egg, pepper, celery, onion):
- Almondfits better
- Chestnutfits better

- Peasthe original
Fit is the average pairing score against butter, flour, cream, egg, pepper, celery, onion. Candidates are from the same food group and used in at least 100 recipes.
