Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Provides the fat base, giving the spread its rich flavor and creamy, spreadable texture.
- Whipped cream
- Adds moisture and air, lightening the butter and making the spread softer.
- Mustard
- Adds sharp, tangy flavor that cuts through the richness of the butter.
The step that matters
Gently mix in the whipped cream. Whipped cream holds its air through folding. Vigorous stirring deflates it and can overwork the fat, leaving the spread dense or grainy.
