Why it works: Parsley and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Fish Croquettes
Ingredients
Directions
Prepare the mixture
Remove bones from the cold fish and break it into pieces.
Heat the butter in a pan.
Stir in the sweet milk and thicken with flour.
Once cooked, add the beaten egg, minced fish, pepper, salt, parsley, and lemon juice.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold fish
- Forms the main body and flavour of the croquettes.
- Butter
- Adds richness and fat that keeps the mixture tender.
- Flour
- Thickens the milk into a binding base that holds the mixture together.
- Beaten egg
- Binds the mixture so the croquettes keep their shape.
- Grated bread crumbs
- Form a crisp, golden coating when fried.
The step that matters
Spread the mixture out to cool. A thick, warm mixture is too soft to shape and will slump or split when formed. Cooling firms the starch and fat so the croquettes hold their shape and fry cleanly.
Swap the parsley
How well each one fits the dish's main ingredients (fish, butter, milk, flour, egg, pepper, lemon):
- Parsleythe original
- Nutmegfits about as well
- Tarragonfits less well
- Cardamomfits less well
Fit is the average pairing score against fish, butter, milk, flour, egg, pepper, lemon. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
