Why it works: Pepper and lemon 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 ↓
Oysters on Toast
Ingredients
Directions
Prepare
Prepare enough buttered toast to fill a platter.
Cook the oysters
Cook the can of oysters in their liquid, seasoning with butter, salt, and pepper.
Pour the cooked oysters over the toast.
Scald a dozen oysters in their own liquor or a little well-salted water, then skim them out.
Make the sauce
In a saucepan, melt 1 tablespoon of butter, add ½ cup of cream, lemon juice, and 1 teaspoon of flour.
Heat the mixture, then add the beaten egg and stir until thickened.
Pour the sauce over the oysters in a hot dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Provide the main savory flavor and the tender, briny body of the dish.
- Butter
- Adds richness and a rounded, savory flavor to the oysters and sauce.
- Cream
- Gives the sauce body and a smooth, rich texture.
- Flour
- Thickens the sauce by swelling with heat to give it body.
- Beaten egg
- Sets into the sauce as it heats, thickening and enriching it.
- Lemon juice
- Adds acidity that brightens the rich cream and butter sauce.
The step that matters
Adding the beaten egg to the sauce. Egg proteins thicken the sauce as they heat, but if the mixture gets too hot or boils after the egg goes in, the egg can curdle and turn grainy. Stir steadily over gentle heat until it just thickens.
