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

What each ingredient does

Mangoes
Provide the main fruit body and sweet, fruity flavor of the relish.
Onions
Add pungent savory flavor that mellows during the long resting and cooking process.
Cabbage
Adds bulk and a crisp, fibrous texture to the finished hash.
Sugar
Adds sweetness that balances the sharpness of the vinegar.
Vinegar
Provides acidity that preserves the mixture and gives it its tang.

The step that matters

Salt the mixture and let it sit overnight. Salt draws water out of the chopped vegetables and fruit through osmosis, softening them and concentrating flavor. Skipping the rest leaves the texture watery and the flavors less developed.
