Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef marrow
- Melts into the sauce, adding richness, body and a rich savory fat flavor.
- Butter
- Adds fat for a smooth, glossy texture and a silky mouthfeel.
The step that matters
Stirring in the butter off the heat. Removing the sauce from heat lets the butter melt gently and blend in smoothly. Over high heat, butter fat can separate from the liquid, leaving the sauce greasy and broken.
