Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Make up the bulk of the sauce and release moisture as they cook.
- Butter
- Adds fat and richness and helps cook the cucumbers gently in the pan.
- Broth or gravy
- Supplies the liquid base and savory flavor of the sauce.
- Onion
- Adds savory sweetness and aroma as it browns in the butter.
- Vinegar
- Adds acidity that brightens the rich, savory sauce.
