Why it works: Horseradish and mustard 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 off a piece from the blossom end of each lemon, leaving a surface the size of a shilling.
Scoop out the insides and wash them in cold water to remove loose pulp.
Immerse the lemons in a brine of 1 pound of coarse sea salt to 1 gallon of water.
Rouse them occasionally and change the brine on the third day, letting them pickle for three more days.
Drain and wipe the lemons dry.
Fill and pack
Fill them with a mixture of horseradish, mustard seed, ginger, eschalots, and chillies.
Stitch the cut pieces back onto the lemons.
Place the lemons closely together in a stone jar.
Pickle and seal
Pour boiling hot pickling liquid made from vinegar, strained lemon juice, table salt, white peppercorns, bruised ginger, and mace over the lemons.
Ensure the lemons are well covered by the pickle, and cover with paper for three days, then top up with more pickle if needed.
Seal the jars with bladder and cover with leather.

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 preserves and flavours.
- Coarse sea salt
- Draws moisture out and seasons the lemon peel during the brine stage.
- Mustard seed
- Adds sharp pungency that mellows as the lemons pickle.
- Pickling vinegar
- Acidifies the liquid, helping preserve the lemons and keep them firm.
The step that matters
Keeping the lemons fully submerged in the pickle. Lemons exposed to air can spoil and grow mould, so keeping every piece covered by the acidic, salty liquid is what preserves them.
Swap the mace
How well each one fits the dish's main ingredients (lemon, horseradish, mustard, ginger, vinegar):
- Turmericfits better
- Tarragonfits better
- Dillfits better
- Macethe original
Fit is the average pairing score against lemon, horseradish, mustard, ginger, vinegar. Candidates are from the same food group and used in at least 100 recipes.
