Why it works: Pepper and horseradish are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 2,646 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

Steam and serve

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, cooked gently by steam to stay moist and tender.
- Butter
- Enriches the sauce with fat, giving it a creamy, smooth texture.
- Horseradish
- Adds sharp, pungent heat that cuts through the richness of the butter.
The step that matters
Steaming the trout for 30 minutes. Steam heat cooks the fish gently; overcooking firms and dries the flesh, while underdone fish stays translucent near the bone. Wrapping in a cloth holds in moisture during cooking.
