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 ↓
Egg Croquettes
Ingredients
Directions
Prepare the filling
Cook the eggs in water just off the boil for 30 minutes.
Once cold, remove the shells and chop the whites finely.
Sift the yolks and mix them with the chopped whites and the slightly beaten egg.
Season with salt, pepper, parsley or chives, and add cooked mushrooms if desired.
Mix in the heavy white sauce and set aside until cold.
Shape, coat and fry
Mould the mixture into croquettes, dip in breadcrumbs, then in the beaten egg.
Fry in hot oil until golden brown.
Serve
Serve with white sauce or add peas, small beans, mushrooms, or asparagus tips.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Hard-boiled yolks and whites form the bulk and body of the croquette filling.
- Heavy white sauce
- Binds the chopped egg into a mixture that holds its shape when moulded.
- Breadcrumbs
- Form a crisp, golden crust that browns in the hot oil.
- Beaten egg
- Acts as a glue so the breadcrumbs stick to the croquettes.
The step that matters
Let the mixture cool completely before moulding. Warm filling is soft and loose, so croquettes may slump or split. Chilling firms the fat and starch in the white sauce so the shapes hold during coating and frying.
Swap the parsley
How well each one fits the dish's main ingredients (egg, pepper, mushroom, sauce):
- Parsleythe original
- Tarragonfits about as well
- Thymefits about as well
- Capersfits less well
Fit is the average pairing score against egg, pepper, mushroom, sauce. Candidates are from the same food group and used in at least 100 recipes.
