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 ↓
White Sauce
Ingredients
Directions
Make the sauce
In a saucepan, bring the stock to a boil, then remove from heat.
In a bowl, beat the cream and egg together, then strain into the saucepan.
Season with pepper and coarse sea salt, then return to low heat.
Stir gently until the sauce thickens like custard, being careful not to boil.
Finish and serve
Strain the sauce and serve with chicken or veal, adding lemon juice if desired.

Egg and lemon barely smell alike, yet cooks put them together in 44,316 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
- Cream
- Adds richness and smooth body to the sauce.
- Egg
- Thickens the sauce as it gently heats, giving it a custard-like set.
- Stock
- Provides the savoury liquid base that the cream and egg thicken.
The step that matters
Stir gently until the sauce thickens like custard, being careful not to boil. Egg proteins set as the sauce heats, but high heat or boiling can curdle the egg and leave the sauce grainy. Gentle, low heat keeps it smooth.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
