Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mustard seed
- Provides the sharp, pungent heat that defines the pickle's flavour.
- Horseradish
- Adds sharp pungency that mellows during long pickling.
- Ginger
- Contributes aromatic warmth and a gently spicy bite.
- Boiling vinegar
- Acidity that preserves the mangoes and sharpens the overall flavour.
- Sugar
- Balances the sharpness of vinegar and mustard with sweetness.
The step that matters
Soaking the mangoes in salt. Salt draws water out of the mangoes through osmosis, firming the fruit and reducing spoilage risk before filling. Skipping or shortening the soak leaves the flesh soft and more prone to spoiling during long storage.
