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 croquette mixture
In a bowl, combine minced fish with cream.
Beat the egg and mix it with milk and flour until smooth.
Combine this mixture with the fish, seasoning with pepper, salt, parsley, and lemon juice.
Shape and coat
Shape the mixture into pear shapes using your hands.
Dip each croquette into beaten egg, then coat with bread crumbs.
Fry and serve
Fry in hot lard until golden brown.
Garnish with parsley and serve with thin slices of buttered brown bread.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold cooked fish
- Forms the main body of the croquettes and gives their savory flavor.
- Cream
- Adds moisture and richness, keeping the filling soft and tender.
- Egg
- Binds the mixture so the croquettes hold their shape.
- Flour
- Thickens the batter-like mixture and helps it bind to the fish.
- Bread crumbs
- Form a crisp, golden coating when fried.
The step that matters
Frying in hot lard. If the lard is not hot enough, the coating absorbs fat and becomes greasy before it browns, and the filling may not set properly. Frying at a steady high heat gives a crisp, golden exterior.
Swap the parsley
How well each one fits the dish's main ingredients (fish, cream, egg, milk, flour, pepper, lemon):
- Nutmegfits about as well
- Parsleythe original
- Tarragonfits about as well
- Cardamomfits about as well
Fit is the average pairing score against fish, cream, egg, milk, flour, pepper, lemon. Candidates are from the same food group and used in at least 100 recipes.
