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 round piece from the blossom end of each lemon, larger than a shilling. Scoop out the insides and rinse with cold water.
Soak the lemons in brine made with 4 ounces of salt and 1 quart of water for 6 days, changing the brine after 3 days.
Drain the lemons and fill them with equal parts mustard seed and horseradish, sliced ginger, and shallots or garlic if desired.
Sew the cut pieces back on the lemons and place them in a stone jar.
Pickle and finish
Prepare a pickle with the strained juice of the lemons, 1 quart of vinegar, 1 teaspoon salt, 1 tablespoon ginger, 1 tablespoon white peppercorns, and 1-2 blades of mace.
Pour the boiling pickle over the lemons.
For quick consumption, place the jar in a cool oven overnight; otherwise, let it stand for 5-6 months.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lemons
- Their rinds and juice supply the sour flavour and soften as the lemons cure in brine and pickle.
- Salt
- Draws water out of the lemons during the brine soak and helps preserve them.
- Vinegar
- Adds acidity that preserves the lemons and gives the pickle its sharp, tangy character.
- Mustard seed
- Contributes pungent flavour that infuses the lemons during the long pickling period.
- Horseradish
- Adds a sharp, pungent heat that mellows as the lemons pickle.
The step that matters
Changing the brine after 3 days. The salt brine draws out moisture and bitterness from the lemons; replacing it partway keeps the soak strong enough to cure the fruit evenly rather than letting the first brine weaken.
Swap the shallot
The recipe marks shallot as optional. How well each one fits the dish's main ingredients (lemon, mustard, horseradish, ginger, vinegar, mace):
- Shallotthe original
- Radishfits about as well
- Broccolifits about as well
- Beetrootfits less well
Fit is the average pairing score against lemon, mustard, horseradish, ginger, vinegar, mace. Candidates are from the same food group and used in at least 100 recipes.
