Why it works: Lemon and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Milk and Egg Sauce,
Ingredients
Directions
Make the sauce
Mix the batter and flour in a saucepan.
Add the milk and heat while stirring constantly until it thickens slightly.
Beat the egg yolk with the water and mix it into the sauce, ensuring it does not boil but is very hot.
Finish and serve
For fish, add vinegar or lemon juice and grated peel, and optionally chopped parsley.
For boiled fowls, add chopped oysters.
For macaroni, layer it with grated cheese and pour the sauce over before baking.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Batter
- Provides body and starch that help thicken the sauce as it heats.
- Flour
- Thickens the milk by swelling its starch as the sauce heats.
- Milk
- Forms the liquid base of the sauce and carries the thickening.
- Egg yolk
- Enriches the sauce and helps it set to a smooth, creamy texture when heated gently.
The step that matters
Adding the egg yolk. If the sauce boils after the egg yolk goes in, the egg proteins can scramble and make the sauce grainy. Keep it very hot but below a boil, and stir well.
