Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the butter and cream into a smooth, body-rich sauce.
- Heavy cream
- Adds richness and a smooth, silky texture to the sauce.
- Butter
- Carries flavor and adds richness as the base of the sauce.
- Anchovies
- Contribute a deep, savory umami flavor that blends into the sauce.
- Lemon juice
- Adds acidity that brightens the rich sauce.
The step that matters
Bring to a boil, stirring well. Flour needs to be heated and kept moving so it thickens smoothly without lumps. Cream can scorch or separate if left unattended on the heat.
Swap the lemon
