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, Baked
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Wash, empty, and dry the trout.
Sprinkle the trout with seasoned flour.
Melt a little butter in a baking tin.
Bake
Place the trout in the tin.
Add several pats of butter on top of the trout.
Bake for about 20 minutes.
Make the sauce and serve
Transfer the trout to a dish.
Garnish the trout with parsley.
Thicken the remaining butter slightly.
Stir in chopped parsley and lemon juice.
Pour the sauce around the fish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Trout
- Forms the main body of the dish, cooking through in the oven while staying moist.
- Butter
- Adds fat and richness, keeping the fish moist while it bakes and forming the base of the sauce.
- Seasoned flour
- Coats the fish, helping it brown lightly and giving the sauce some body.
- Lemon juice
- Adds acidity that brightens the buttery sauce and balances its richness.
The step that matters
Thicken the remaining butter slightly. Butter that is heated too long or too far can brown or separate, so it should be warmed only until it thickens gently. Keeping the heat low helps the sauce stay smooth and pourable.
