Sugar and milk 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

Confectioners' sugar
Dissolves into the liquid and stiffens it, giving the frosting body and sweetness.
Water or milk
Liquid that dissolves the sugar into a smooth, spreadable frosting.
Chocolate
Adds chocolate flavor and color to the frosting.

The step that matters

Adding more sugar when the frosting is too thin. Sugar dissolves into the liquid and thickens the mixture, so adding it gradually lets you stop at a spreadable texture. Adding too much liquid or too much sugar at once makes the frosting hard to correct.
