Why it works: Mustard and horseradish match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,832 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Green Mangoes
Ingredients
Directions
Prepare the mangoes
Wash the mangoes and soak them in strong salt water for 3–4 weeks.
Soak the mangoes in cold water for 5–6 hours before greening them.
Green the mangoes with alum and grape leaves.
Place the mangoes in a tub of cold water until cold, then remove the insides and put them in vinegar for 2 weeks.
Stuff and pack
In a bowl, mix the mustard seeds, mace, celery seed, and horseradish until half pounded.
Add the sweet oil to the mixture and stuff the mangoes.
Tie the mangoes with yarn and place them in jars with the peeled onions.
Make the pickle and sun-cure
In a separate bowl, combine the sugar, horseradish, long pepper, allspice, and celery seed with vinegar.
Stir well, cover the jars tightly, and place them in the hot sun for 3–4 weeks.
Cover the jars with bladders and keep them sealed.
Check the jars every month or two, adding more vinegar if necessary to keep the mangoes covered.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mangoes
- Form the main body of the pickle, absorbing the stuffing and vinegar flavours as they cure.
- Sugar
- Adds sweetness that balances the sharp vinegar and horseradish.
- Cider vinegar
- Acid that preserves the mangoes and gives the pickle its sharp tang.
- Mustard seed
- Provides pungent heat and texture in the stuffing.
- Horseradish
- Contributes sharp, pungent heat that mellows during curing.
- Sweet oil
- Adds fat and moistness to the stuffing, carrying its spice flavours.
The step that matters
Keeping the mangoes covered in vinegar. Any part of the mangoes left above the liquid can spoil or mould during the long sun-curing. Vinegar, being acidic, preserves the fruit only where it fully covers it, so topping up is essential.
