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 the pulp and skin using the handle of a teaspoon.
Rinse the insides until the water runs clear.
Brine
Soak the lemons in a brine made with ½ pound of salt and 2 quarts of water for 3 days, stirring often.
Change the brine and soak for an additional 3 days.
Fill and pickle
Drain the lemons and fill them with mustard seed, chilies, horseradish, shallots, and ginger.
Sew the cut pieces back onto the lemons.
Place the lemons in a stone jar and pour boiling pickle made from their juice, vinegar, salt, ginger, 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 main body and acidic juice that the pickle is built around.
- Coarse sea salt
- Draws water out of the lemons during brining and seasons the fruit thoroughly.
- Lemon juice
- Adds acidity and sharp flavour to the pickling liquid that preserves the lemons.
- Vinegar
- Adds acidity to the pickle, helping to preserve the lemons and sharpen their flavour.
- Mustard seed
- Contributes pungent, sharp flavour that mellows as the lemons pickle.
The step that matters
Changing the brine and soaking the full six days. Salt slowly draws water and bitterness out of the peel and pulp. Skipping the fresh brine or shortening the soak leaves the lemons salty, bitter, and less evenly cured.
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.
