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 ↓
Lemon Mangoes
Ingredients
Directions
Prepare the lemons
Cut a circular piece of rind from the blossom end of each lemon.
Scoop out the pulp and skin using a teaspoon handle. Rinse the insides until the water runs clear.
Brine
Soak the lemons in brine made with ½ pound of salt and 2 quarts of water, stirring often.
After 3 days, change the brine and soak for another 3 days.
Fill and finish
Drain the lemons and fill them with mustard seed, chilies, horseradish, shallots, and ginger.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lemons
- Provide the fruit and rind that soften and turn tender during the long brine soak.
- Coarse sea salt
- Draws water out of the lemons and preserves them, seasoning them throughout.
- Mustard seed
- Adds pungent, sharp flavour to the filling as the lemons cure.
- Small chilies
- Add heat that mellows and infuses the lemons during curing.
- Young scraped horseradish
- Adds sharp, pungent heat to the filled lemons.
The step that matters
Changing the brine after 3 days. Salt is drawn out of the brine as it soaks into the lemons and the brine becomes diluted and cloudy with fruit juice. Replacing it restores the salt concentration needed to preserve the lemons safely through the full curing period.
Swap the ginger
How well each one fits the dish's main ingredients (lemon, mustard, horseradish, shallot):
- Capersfits better
