Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tench
- Is the main fish that is cooked and served in the stewing liquid.
- Butter
- Enriches the sauce with fat and rich flavour as it melts into the liquid.
- Flour
- Thickens the butter and wine or cider into a smooth base for the sauce.
- Egg yolks
- Enrich and thicken the sauce when gently heated, giving it a silky texture.
- French wine or cider
- Provides the cooking liquid that stews the fish and gives the sauce acidity and flavour.
The step that matters
Stirring the egg yolks into the sauce over low heat. Egg yolks thicken by gentle heat; if the sauce gets too hot or boils, the yolks can scramble and curdle, leaving the sauce grainy instead of smooth.
Swap the onion
How well each one fits the dish's main ingredients (butter, flour, wine, parsley, thyme, pepper, egg):
