Why it works: Onion and beef are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,092 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Common Carp Stewed in Rich Gravy
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the fish
Clean and gut the carp, then rinse it under cold water.
Make the broth base
In a large pot, melt the butter over medium heat and sauté the chopped onion until translucent.
Add the flour and stir for 1 minute to create a roux.
Gradually add the broth, stirring constantly until the mixture thickens.
Simmer and serve
Season with salt and pepper, then add the carp to the pot.
Cover and simmer for 30-40 minutes until the fish is cooked through.
Serve hot, garnished with fresh herbs.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Common carp
- Forms the main body of the stew and provides the protein.
- Butter
- Adds fat and richness to the onions and roux.
- Onion
- Adds sweetness and savory depth as it softens in the butter.
- Flour
- Thickens the broth as a roux, giving the stew body.
- Beef or vegetable broth
- Forms the liquid base that the stew cooks and thickens in.
The step that matters
Thickening the broth with the roux. Flour must be cooked briefly in fat before liquid is added, and broth must be added gradually while stirring. This cooks out the raw flour taste and prevents lumps, so the broth thickens smoothly.
