Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed butter forms the rich base that carries the other flavours and gives the sauce body.
- Lemon juice
- Adds acidity that brightens the rich butter and balances the sauce.
- Mayonnaise
- Its emulsifiers help the butter and lemon juice combine into a smoother, more cohesive sauce.
The step that matters
Combine the mayonnaise well. Butter and lemon juice do not stay mixed on their own. Mayonnaise contains emulsifiers that help hold the fat and liquid together, so the sauce stays smooth rather than separating.
