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 ↓
Egg Sauce
Ingredients
Directions
Boil the milk and water.
Add the butter, pepper, and salt.
Thicken the sauce with the cornflour.
Beat the egg with the lemon juice.
Remove the sauce from the heat and gradually add the egg mixture, stirring gently to avoid curdling.
Warm the sauce again, but do not allow it to boil.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Beaten egg enriches the sauce and thickens it gently when warmed, giving it a silky body.
- Cornflour
- Starch swells in hot liquid to thicken the sauce into a smooth coating consistency.
- Butter
- Adds fat for a rich mouthfeel and a smooth, glossy finish.
- Lemon juice
- Adds acidity that brightens the flavour and balances the richness of the butter and egg.
The step that matters
Adding the egg mixture. Egg proteins set when heated, so adding the beaten egg to a hot sauce can scramble it. Removing the pan from the heat first and stirring gently helps keep the sauce 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.
