Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Small peppers
Provide the pepper flavor and heat that steep into the vinegar.
Sugar
Adds sweetness that softens the sharpness of the vinegar.
Cider vinegar
Provides the acidity that extracts and carries the pepper flavor.

The step that matters

Seal and let it sit. The vinegar needs time to draw flavor and heat out of the peppers and to dissolve the sugar. Using it too soon gives a harsh, thin taste, so the full rest matters.
