Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Milk
Provides the proteins that curdle into curds, leaving the clear whey behind.
Vinegar or lemon juice
Acid that causes the milk proteins to curdle and separate, releasing the whey.
Sugar
Adds sweetness to balance the sharpness of the acid.

The step that matters

Pouring in the vinegar or lemon juice. Acid must be added while the milk is boiling so the proteins curdle fully and separate cleanly. Adding too little leaves the milk cloudy, and adding too much makes the whey harsh and sour, which is why the recipe asks for dilution with hot water and tasting for sweetness.
