Why it works: Egg and milk are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 88,785 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
A Very Good and Useful White Sauce
Ingredients
Directions
Make the sauce
In a stew‑pan, heat 1 quart of white sauce over medium heat, stirring continually until reduced to one-third.
In a bowl, whisk 2 egg yolks, then gradually add the reduced sauce while stirring.
Return the mixture to the stew‑pan and bring to a boil for a few minutes.
Add 1 pint of boiling milk to achieve the desired thickness, which should coat the back of a spoon.
Strain and store
Strain the sauce through a fine sieve into a bowl and stir occasionally until cool.
If not using immediately, store in a covered container in the refrigerator for up to 2‑3 weeks in winter or 1 week in summer.

Sauce and egg barely smell alike, yet cooks put them together in 10,895 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
- Egg yolks
- Add richness and help thicken the sauce as they set with gentle heat.
- White sauce
- Forms the base of the sauce, and reducing it concentrates its body and flavour.
- Milk
- Adds liquid to loosen the sauce and bring it to the desired thickness.
The step that matters
Returning the egg yolk mixture to the pan. Egg yolks thicken by gentle heat but can scramble if the sauce gets too hot too fast. Keep the heat moderate and stir constantly so the sauce thickens smoothly.
