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

What each ingredient does

Butter
Provides fat and richness, and creams with the sugar to give the sauce a smooth body.
Powdered sugar
Adds sweetness and dissolves easily, helping the sauce become light and smooth when beaten.
Brandy
Adds aroma and a warm alcohol flavor that balances the richness of the butter and sugar.

The step that matters

Beat until very light and frothy. Beating air into the creamed butter and sugar gives the sauce its light, smooth texture. Under-beating leaves it dense and grainy, while the chilling step firms it for serving.

Swap the orange

The recipe marks orange as optional. How well each one fits the dish's main ingredients (butter, sugar, brandy, lemon):

  1. Vanillafits about as well
  2. Orangethe original
  3. Apricotfits about as well
  4. Figfits about as well

Fit is the average pairing score against butter, sugar, brandy, lemon. Candidates are from the same food group and used in at least 100 recipes.
