Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Provides fat that gives the spread its rich, smooth body.
- Castor sugar
- Sweetens the spread and helps it cream into a light, smooth texture.
- Egg yolks
- Add richness and emulsify with the butter to hold the mixture smooth.
The step that matters
Cream the sugar and egg yolks for about 10 minutes. Creaming beats air into the sugar and yolks and dissolves the sugar grains, so the mixture becomes pale and smooth. Stopping early leaves grainy sugar and a dense, uneven texture in the finished butter.
