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 ↓
Trout Croquettes
Ingredients
Directions
Prepare the filling
Mince the cold trout as fine as possible.
Season with salt, pepper, and minced parsley.
Combine the fish, bread crumbs, and cream sauce in a saucepan and heat until thick and smooth.

Shape and fry

Fry in deep hot oil until golden brown. Drain on paper towels.
Serve

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold cooked trout
- Provides the main body and flavor of the croquettes.
- Cream sauce
- Adds moisture and richness, helping the mixture bind and turn smooth.
- Bread crumbs
- Thicken the mixture and form a crisp golden coating when fried.
- Egg
- Binds the coating so the crumbs stick to each croquette.
The step that matters
Cooling until cool and firm before shaping. If the mixture is still warm or soft, it will not hold its shape and may fall apart in the hot oil. Thorough cooling lets the starch and proteins set so the croquettes keep their form.
