Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Celery
- Provides the main vegetable bulk and crisp, fresh texture in the relish.
- Red peppers
- Adds sweetness, colour and a mild vegetable body to the relish.
- Vinegar
- Provides the acidity that preserves the relish and gives it its sharp flavour.
- Flour
- Thickens the cooking liquid so the relish becomes less watery.
- Sugar
- Balances the sharpness of the vinegar with sweetness.
- Curry powder
- Contributes the warm, spiced aroma that defines the relish.
The step that matters
Dissolve the flour, mustard and curry in vinegar before adding to the pot. Flour clumps easily when it meets hot liquid directly. Mixing it first into a small amount of cool vinegar gives a smooth slurry that blends evenly and thickens without lumps.
Swap the celery
How well each one fits the dish's main ingredients (pepper, vinegar, mustard, flour, sugar):
- Tarragonfits better
