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
Provides the proteins that clump into curds when acid is added, leaving clear whey behind.
Vinegar
Its acidity makes the milk proteins clump, separating curds from the liquid whey.
Sugar
Adds a touch of sweetness to the finished whey.

The step that matters

Let it sit until the whey separates. Straining too early pushes soft, unformed curds through the strainer and cloudy liquid results. Waiting lets the acid finish clumping the milk proteins, so the whey runs clear.
