Why it works: Butter and oyster are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 8,184 recipes. Both carry 2,6-nonadienal, which smells cucumber, green. The science ↓
Filleted Soles
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the stuffing
Combine egg yolks, butter, and chopped parsley in a small saucepan.
Stir over low heat until thickened.
Fill and bake the fillets
Cut each sole into four fillets.
Spread some egg mixture on one side of each fillet, then fold over.
Place the fillets in a Yorkshire pudding dish.
Bake at 400°F (200°C) until the fish is cooked through.
Make the sauce and serve
Make oyster sauce using stock instead of water.
Add a little chopped parsley to the sauce.
Arrange the fillets in a crown on a serving dish.
Pour the sauce in the center.
Serve.

Butter and sauce barely smell alike, yet cooks put them together in 15,338 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken when gently heated, forming the creamy filling that holds the fillets together.
- Butter
- Adds richness and moisture, helping the egg mixture stay smooth and soft.
- Soles
- Provide the delicate white fish that is filled, folded, and baked.
The step that matters
Stir over low heat until thickened. Egg yolks thicken through gentle heat; if the heat is too high they scramble and curdle instead of forming a smooth, pourable mixture.
Swap the parsley
How well each one fits the dish's main ingredients (egg, butter, oyster, sauce):
- Capersfits better
- Parsleythe original
- Nutmegfits about as well
- Tarragonfits about as well
Fit is the average pairing score against egg, butter, oyster, sauce. Candidates are from the same food group and used in at least 100 recipes.
