Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
To Pickle Lemons, and Limes
Ingredients
Directions
Prepare the lemons
Wash eight lemons very clean.
Make four deep incisions in each lemon from stalk to blossom end, without cutting through.
Stuff lemons with as much salt as they will contain.
Place lemons in a deep dish and put in a sunny window or warm place for a week or ten days, turning and basting with their own liquor often.
Rub lemons with good pale turmeric.
Make the pickle
Put lemons with their juice into a stone jar with a small head of garlic (cloves peeled) and a dozen small onions with twice as many cloves.
Boil two quarts of white wine vinegar, half a pound ginger slightly bruised, two ounces whole black pepper, and half a pound mustard-seed.
Take the boiling mixture from the fire and pour it directly over the lemons.
Cover the jar with a plate and let it remain until the following day.
Add half a dozen capsicums (or a few chilies) to the pickle.
Tie a skin and a fold of thick paper over the jar.
Pickle the limes
Make slight incisions in lime rinds.
Let limes soften for four or five days.
Add two ounces salt for half a dozen limes.
Put limes with their juice into jar before vinegar is poured.
Mix vinegar with spices and mustard-seed, boil, then pour over limes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lemons
- Supply sour juice and peel that softens and flavours the pickle as it sits.
- White wine vinegar
- Provides sharp acidity that preserves the fruit and gives the pickle its tang.
- Ginger
- Adds warm, fresh aroma and a gentle spiciness to the pickle.
- Mustard-seed
- Adds a sharp, pungent bite that cuts through the sour fruit.
- Garlic
- Adds savoury aroma that deepens as the pickle matures.
The step that matters
Pouring the boiling mixture over the lemons. The hot vinegar softens the peel and carries the acid and spices into the fruit quickly. Letting it cool first would weaken that penetration, so it should go over the lemons straight from the fire.
Swap the ginger
