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 of rind from the blossom end of each lemon.
Scoop out the pulp and skin using a teaspoon handle. Rinse the insides until the water runs clear.
Brine
Soak the lemons in brine made with ½ pound salt and 2 quarts water for 6 days, changing the brine after 3 days.
Fill and pickle
Drain the lemons and fill them with mustard seed, chilies, horseradish, shallots, and ginger.
Sew the cut pieces back on the lemons.
Place the lemons in a stone jar.
Pour boiling pickle made from 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 main body and acidic juice that the pickle is built around.
- Sea salt
- Draws water out of the lemons and seasons them during the long brine soak.
- Lemon juice
- Adds acidity and tang to the pickling liquid that preserves the lemons.
- Vinegar
- Adds further acidity to the pickle, helping to preserve and sharpen the flavour.
- Mustard seed
- Adds a sharp, pungent flavour that infuses the lemons as they pickle.
The step that matters
Six-day brine soak. The brine must fully penetrate the rind and pulp so the lemons soften and season evenly. Changing the brine after three days keeps the salt strong enough to work through the fruit.
