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

What each ingredient does

Butter
Creamed with sugar to build a light, soft, spreadable texture and rich flavor.
Powdered sugar
Sweetens the sauce and dissolves smoothly into the butter for a fine, creamy texture.
Egg
Beaten in to add richness and help the mixture turn white and airy.

The step that matters

Beating until white and light. Beating the butter and sugar until very light traps air, and adding the egg gradually while beating keeps the emulsion smooth rather than curdled.
