Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and 27,039 recipes mention both. Both carry 2-nonenal, which smells fatty, green. The science ↓
The recipe
Ingredients
Contains: egg, milk, wheat, shellfish (auto-detected from the ingredients and method; we can miss things, so check labels)
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 fish
Skin and fillet the sole, folding each fillet over.
Butter a tin dish and place the fillets in it without overlapping.
Sprinkle with pepper, salt, and a few drops of vinegar or lemon juice.
Butter a piece of paper thickly and cover the tin with it.
Bake in a 400°F (200°C) oven for 10 minutes.
Make the stock and sauce
In a small saucepan, combine the skin and bones of the sole, herbs, bay leaf, onion, carrot, and stock or water, and boil for 30 minutes.
Scald the oysters in their own liquor, strain, and add the oyster liquor to the stock, boiling for an additional 10 minutes.
In a small saucepan, melt 1 oz of butter and stir in 1 oz of flour until smooth.
Strain the stock into the flour mixture and stir until smooth, then add the cream.
Pour the cooking liquid from the tin into the sauce and bring to a boil, seasoning to taste.
Remove from heat and stir in the egg yolks until smooth.
Serve
Arrange the fillets in a circle on a serving dish.
Pour the sauce over the fillets and place the oysters in the center.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sole
- Provides the delicate white fish fillets that form the base of the dish.
- Oysters
- Add a briny, savoury flavour to the sauce and garnish the finished dish.
- Butter
- Enriches the sauce with fat and flavour, and keeps the fish from sticking.
- Flour
- Thickens the stock into a smooth sauce when cooked with the butter.
- Egg yolks
- Enrich and thicken the sauce, giving it a smooth, velvety texture.
- Cream
- Adds richness and mellows the sauce's texture.
The step that matters
Stirring in the egg yolks off the heat. Egg yolks thicken by gentle heat; if the sauce is too hot or boils after they are added, they can scramble and turn grainy, so the sauce must be removed from the heat first.

Fit is the average pairing score against oyster, carrot, turnip, onion, egg, cream, pepper. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
