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, about the size of a shilling.
Scoop out all the pulp and skin using the handle of a teaspoon.
Rinse the insides of the rinds until the water runs clear.
Brine
Soak the rinds in a 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 pickle
Drain the rinds and fill them with mustard seeds, chilies, horseradish, shallots, and ginger.
Sew the cut pieces back on the lemons.
Place the lemons in a stone jar and pour boiling pickle made from their juice, vinegar, salt, ginger, white peppercorns, and mace over them.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lemons
- Provide the rinds that are hollowed out and filled, and the juice that makes up the pickle.
- Coarse sea salt
- Draws water out of the rinds during brining, firming them and seasoning the lemons.
- Vinegar
- Adds acidity to the pickling liquid, helping preserve the lemons and sharpening their flavour.
- Mustard seeds
- Add a pungent, slightly bitter flavour to the filling inside the lemons.
The step that matters
Changing the brine after 3 days. The first brine soaks up the lemons' bitterness and salt is what preserves them, so a fresh brine is needed to keep the rinds firm and to keep the pickle from spoiling. Keeping the brine strong and renewing it as the record says matters for a safe, well-seasoned result.
Swap the mace
How well each one fits the dish's main ingredients (lemon, mustard, horseradish, shallot, ginger, vinegar):
- Capersfits better
- Tarragonfits better
- Turmericfits better
- Macethe original
Fit is the average pairing score against lemon, mustard, horseradish, shallot, ginger, vinegar. Candidates are from the same food group and used in at least 100 recipes.
