Why it works: Onion and white wine are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 4,535 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
White-wine Sauce for Sole
Ingredients
Directions
Poach the sole
Clean and trim the sole, then place it in a shallow fish kettle.
Sprinkle the diced onion over the fish, then add salt, sweet herbs, peppercorns, and clove.
Pour enough white wine over the sole to cover it and boil gently until cooked through.
Make the sauce
Strain the cooking liquid into a small saucepan and place it by the fire.
Gradually stir in the egg yolk until the sauce thickens, then remove from heat.
Pour the sauce over the fish before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sole
- Is the main protein, cooked gently in the wine until just firm and flaky.
- French white wine
- Provides the cooking liquid and acidity that flavours both the fish and the sauce.
- Egg yolk
- Thickens the strained liquid into a sauce as its proteins set with gentle heat.
- Onion
- Adds aromatic sweetness and flavour to the poaching liquid.
The step that matters
Stirring in the egg yolk. Egg yolk thickens when heated gently, but if the liquid is too hot or added too quickly it can scramble. Stir gradually and remove from heat as soon as the sauce thickens.
Swap the clove
How well each one fits the dish's main ingredients (onion, white wine, egg):
- Garlicfits better
- Thymefits better
- Tarragonfits better
- Clovethe original
Fit is the average pairing score against onion, white wine, egg. Candidates are from the same food group and used in at least 100 recipes.
