Why it works: Flour and horseradish match in chemistry and in kitchens. They rank in the top 10% of all ingredient pairs, and cooks put them together in 743 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carp
- Is the main protein, which turns flaky and tender as it stews.
- White wine
- Adds acidity and aroma to the braising liquid, helping flavour the fish and sauce.
- Egg yolk
- Thickens and enriches the sauce as it gently heats.
- Cream
- Adds richness and body to the sauce.
- Horseradish
- Adds sharp pungency that cuts through the richness of the cream and yolk.
The step that matters
Stirring the egg yolk into the sauce. Egg yolk thickens when heated gently, but if the sauce gets too hot it can curdle and turn grainy. Stir it in off the heat or over low heat.
