Why it works: Parsley and pepper 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
Press the hard-boiled eggs through a vegetable press or chop them finely.
In a saucepan, melt the butter and add the flour, stirring until combined.
Gradually add the milk and stir until boiling.
Mix in the bread crumbs, salt, parsley, pepper, and onion juice.
Add the pressed eggs and mix well, then let the mixture cool.
Shape and fry
Once cool, form the mixture into cutlets.
Dip each cutlet in egg and then in bread crumbs.
Fry the cutlets in hot oil until golden brown.
Serve
Serve with plain cream sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled eggs
- Bind the mixture and give the croquettes their body and filling texture.
- Butter
- Fat that starts the roux and adds richness to the filling.
- Flour
- Thickens the butter and milk into a sauce that holds the filling together.
- Milk
- Liquid that cooks with the flour into a thick, creamy binding sauce.
- Bread crumbs
- Stiffen the filling and form the crisp, golden outer coating.
The step that matters
Let the mixture cool before shaping. A warm, soft filling will not hold its shape and can split or slump when handled and fried. Cooling lets the starch-thickened sauce set so the cutlets keep their form.
Swap the onion
How well each one fits the dish's main ingredients (egg, butter, flour, milk, bread, parsley, pepper):
- Shallotfits better
- Chivefits better
- Potatofits better
- Onionthe original
Fit is the average pairing score against egg, butter, flour, milk, bread, parsley, pepper. Candidates are from the same food group and used in at least 100 recipes.
