Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cabbage
- Forms the bulk of the relish and gives it a crisp, sturdy texture.
- Cucumbers
- Add crunch and fresh moisture that softens partly when salted and scalded.
- Onions
- Contribute sharp, savory flavor that mellows during scalding and storage.
- Mustard
- Adds pungent, tangy flavor characteristic of the relish.
- Turmeric
- Gives the relish its yellow color and an earthy, slightly bitter flavor.
- Sugar
- Balances the vinegar's acidity with sweetness, adjusted to taste.
The step that matters
Scalding the vegetables until wilted. Heat softens the cabbage and cucumbers and draws out water, so they take up the vinegar and seasonings. Overheating turns them mushy, while underheating leaves them raw and watery in the jar.
