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
Boil the eggs hard, then drop them in cold water.
Squeeze the eggs through a potato ricer.
In a saucepan, melt the butter, then stir in the flour and sweet milk to make a thick sauce.
Add the squeezed eggs, parsley, onion juice, pepper, and salt to the sauce.
Transfer the mixture to a plate and let it cool for three hours.
Shape and fry
Shape the mixture into croquettes.
Dip the croquettes in beaten eggs.
Roll the croquettes in bread crumbs.
Fry the croquettes in boiling lard until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide the bulk and rich flavor of the filling.
- Flour
- Thickens the melted butter and milk into a sauce that binds the filling.
- Sweet milk
- Forms the liquid base of the sauce, adding moisture and softness.
- Butter
- Adds fat and richness to the sauce.
- Bread crumbs
- Form a crisp, golden outer coating when fried.
The step that matters
Cooling the mixture. The filling must cool and firm fully before shaping; a warm, soft mixture will not hold its shape and may split or spread in the hot lard.
Swap the onion
How well each one fits the dish's main ingredients (egg, milk, butter, flour, parsley, pepper, bread):
- Shallotfits better
- Chivefits better
- Potatofits better
- Onionthe original
Fit is the average pairing score against egg, milk, butter, flour, parsley, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
