Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Croquettes and Fritters
Ingredients
Directions
Make the filling
In a saucepan, bring 1 cup of milk to a boil.
Thicken the milk with 1 tablespoon of butter and 2 tablespoons of flour mixed together.
Remove from heat and stir in the beaten yolks of 2 eggs, seasoning with salt, cayenne, black pepper, and minced parsley.
Let the mixture cool on a large dish, then form into croquettes.
Coat and fry
Dip each croquette first in beaten egg, then roll in grated bread crumbs.
Fry the croquettes in boiling 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.

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
- Milk
- Forms the liquid base that the flour thickens into a smooth, spreadable filling.
- Flour
- Thickens the milk into a paste that sets as it cools, letting the croquettes hold their shape.
- Butter
- Adds richness and flavour to the filling and helps keep it smooth.
- Eggs
- Yolks enrich and bind the filling, while the beaten egg helps bread crumbs stick.
- Grated bread crumbs
- Form a crisp outer coating that browns when fried.
The step that matters
Let the mixture cool before forming. The flour-thickened filling firms as it cools. Shaping it while still warm makes the croquettes soft and likely to slump or break when coated and fried.
Swap the parsley
How well each one fits the dish's main ingredients (milk, butter, flour, egg, pepper, bread):
- Nutmegfits about as well
- Cinnamonfits about as well
- Parsleythe original
- Capersfits less well
Fit is the average pairing score against milk, butter, flour, egg, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
