Why it works: Lemon and parsley 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 ↓
Baked Trout
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Bake the trout
Preheat the oven to 400°F (200°C).
Bake the trout for 12 minutes per pound, basting with melted butter three or four times.
Make the sauce
In a saucepan, melt 1 tablespoon of butter and stir in 1 tablespoon of flour until combined.
Once the fish is done, strain the pan juices into the saucepan and stir until thickened.
Add salt, pepper, caramel, and 1 tablespoon of lemon juice, then mix in ½ cup of chopped shrimp.
If the sauce is too thick, reduce it with boiling water and boil for 1 minute.
Serve
Garnish the fish with parsley and lemon before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Trout
- Is the main protein; cooks through in the oven while basted with butter.
- Butter
- Adds richness and moisture while basting the fish and forming the sauce base.
- Flour
- Thickens the pan juices into a smooth sauce when cooked with melted butter.
- Shrimp
- Adds savoury flavour and texture to the sauce.
The step that matters
Thickening the sauce. Flour must be cooked briefly in the melted butter before liquid is added, otherwise it stays starchy and lumpy. Adding too much boiling water thins the sauce, so reduce it gently.
