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 salt and 2 quarts water for 3 days, stirring often.
Change the brine and soak for an additional 3 days.
Fill and pickle
Drain the rinds and fill them with mustard seed, chilies, horseradish, shallots, and ginger.
Sew the cut pieces back onto the lemons and place them in a stone jar.
Pour boiling pickle made from the lemon juice, vinegar, 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
- Provide the edible rind that is salted, softened and filled to become the pickle.
- Coarse sea salt
- Draws moisture out of the rinds and seasons them during the long brine soak.
- Lemon juice
- Supplies acidity that preserves the pickle and gives it a sharp, bright flavour.
- Vinegar
- Adds further acidity to the pickling liquid, helping to preserve the lemons.
- Mustard seed
- Adds a pungent, sharp flavour to the filling inside the rinds.
The step that matters
Changing the brine. The first brine soak draws out bitterness and moisture from the rinds, so a fresh brine for the second soak keeps the salt strength consistent and the rinds properly seasoned and firm.
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.
