Milk and sugar barely smell alike, yet cooks put them together in 77,875 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

Milk
Its proteins coagulate when acid is added, separating into curds and clear whey.
Vinegar or lemon juice
Acid causes the milk proteins to clump, which lets the clear whey separate out.
Hot water
Dilutes the acidity so the whey tastes pleasantly tart rather than sharp.
Sugar
Adds sweetness that balances the remaining sourness of the acidic whey.

The step that matters

Adding the acid to boiling milk. Acid makes milk proteins clump and separate into curds and clear whey. Add it gradually and stop once the liquid runs clear, because too much acid leaves the whey harsh and sour.
