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 from the blossom end of each lemon and scoop out the pulp and skin with a teaspoon.
Rinse the insides of the rinds until the water runs clear.
Brine
Soak the rinds in a brine made of ½ pound of salt and 2 quarts of water for 6 days, changing the brine after 3 days.
Fill and pickle
Drain the rinds and fill them with mustard seeds, chilies, horseradish, shallots, and ginger.
Sew the cut pieces back on, place the lemons in a stone jar.
Pour boiling pickle made from the lemon juice, vinegar, 1 tablespoon of salt, ginger, white peppercorns, and mace over the lemons.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lemons
- Their rinds form the edible case, and their juice becomes part of the pickling liquid.
- Coarse sea salt
- Draws out moisture and seasons the rinds during the long brine soak.
- Vinegar
- Adds acidity to the pickle, helping preserve the lemons and sharpen their flavour.
- Mustard seeds
- Add a pungent, sharp flavour that stands up to the sour lemon rinds.
The step that matters
Soak the rinds in the brine for the full 6 days. Salt slowly draws moisture and bitterness out of the rinds and seasons them through. Changing the brine after 3 days keeps the salt strong enough to do this work, so a shortened soak leaves the rinds harsh and under-seasoned.
Swap the ginger
How well each one fits the dish's main ingredients (lemon, mustard, horseradish, shallot, vinegar):
- Capersfits better
- Tarragonfits better

Fit is the average pairing score against lemon, mustard, horseradish, shallot, vinegar. Candidates are from the same food group and used in at least 100 recipes.
