Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Oyster Duxelles
Ingredients
Directions
Prepare the oysters
Place the oysters in a saucepan over high heat until they begin to ruffle, then remove and drain.
Make the sauce
In the same pan, cook the mushrooms in butter for 5 minutes.
Add the flour and stir until slightly colored.
Gradually add the hot oyster liquor, stirring until thick and smooth.
Simmer for 4 to 5 minutes, then stir in the beaten egg yolk, lemon juice, salt, and pepper.
Add the oysters and mix well.
Serve
Serve the mixture on rounds of hot buttered toast.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Oysters
- Provide the main seafood flavour and the tender texture of the dish.
- Mushrooms
- Add earthy flavour and body to the duxelles base.
- Butter
- Adds richness and carries flavour while cooking the mushrooms.
- All-purpose flour
- Thickens the oyster liquor into a smooth, stable sauce.
- Egg yolk
- Enriches and thickens the sauce, giving it a smooth, creamy body.
The step that matters
Gradually add the hot oyster liquor, stirring until thick and smooth. Adding liquid to flour gradually while stirring keeps starch from clumping into lumps. Starch thickens as it heats, so the sauce becomes smooth and holds together.
