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 ↓
Egg Sauce
Ingredients
Directions
Make the sauce
Heat water and milk in a saucepan until hot.
Mix flour with a little cold water until smooth.
Stir the flour mixture into the hot water and milk.
Add beaten and strained eggs, and season with salt, pepper, butter, and vinegar.
Do not let the sauce boil after adding the eggs.
Garnish and serve
Slice the hard-boiled eggs and lay them over the sauce.
Optionally, add nutmeg and lemon slices before serving with boiled fish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the milk and water into a smooth, body-rich sauce.
- Eggs
- Enrich the sauce and thicken it gently when heated without boiling.
- Butter
- Adds fat for a rounded, smooth mouthfeel and richer flavor.
- Milk
- Adds creaminess and mild sweetness to the sauce base.
The step that matters
Do not let the sauce boil after adding the eggs. Egg proteins set and curdle when overheated, so the sauce turns grainy or lumpy. Keeping it below a boil preserves a smooth, thickened texture.

Fit is the average pairing score against milk, flour, egg, pepper, butter, vinegar, nutmeg. 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).
“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.
