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
Make the mixture
Flake the fish with a silver fork and mix in the pepper, salt, parsley, lemon juice, and Thick White Sauce.
Spread the mixture on a plate to cool.
Coat and fry
Shape the mixture into croquettes, then roll them in cracker crumbs, dip in the beaten egg, and coat again with cracker crumbs.
Fry the croquettes in deep hot oil until golden brown.
Drain on brown paper and serve with Egg, Hollandaise, or Tartare Sauce. Garnish with sliced lemon and parsley.

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 croquette, giving the filling its flavor and texture.
- Thick white sauce
- Binds the flaked fish together so the croquettes hold their shape.
- Egg
- Coats the croquettes so the cracker crumbs stick and form a crisp outer layer.
- Cracker crumbs
- Form a golden, crisp crust when fried in hot oil.
The step that matters
Cooling the mixture before shaping. A warm, soft mixture is hard to shape and can fall apart. Cooling firms the binding sauce so the croquettes hold together through coating and frying.
“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.
