Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Provides fat that makes the sauce rich and gives it a smooth, spreadable body.
- Powdered sugar
- Adds sweetness and dissolves into the butter, giving the sauce a fine, smooth texture.
The step that matters
Creaming the butter and powdered sugar together. Beating the softened butter with sugar traps air and blends the two evenly, so the sauce turns light and smooth rather than greasy or grainy.
