Why it works: Turmeric and ginger match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 2,776 recipes. Both carry eucalyptol, which smells eucalyptus, herbal. The science ↓
To Pickle Lemons, and Limes
Ingredients
Directions
Prepare the lemons
Wipe the lemons clean and make four deep incisions in each, from stalk to blossom end, without dividing the fruit.
Stuff the lemons with salt and place them in a deep dish in a sunny spot for 7 to 10 days, turning and basting them with their own juice.
Pack and pickle
Rub the lemons with turmeric, then place them in a stone jar with garlic and onions.
Boil the vinegar with ginger, black pepper, and mustard seed, then pour it over the lemons.
Cover the jar with a plate and let it sit until the next day.
Add capsicums or chilies, then seal the jar with a skin and thick paper.
Finish
For immediate use, place the lemons in a cool oven overnight.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lemons
- Their peel and juice supply the main sour flavour and aroma of the pickle.
- Coarse sea salt
- Draws out juice and preserves the lemons by inhibiting spoilage microbes.
- White wine vinegar
- Adds acidity that preserves the lemons and sharpens the brine.
- Ginger
- Contributes a warm, aromatic pungency to the brine.
- Mustard seed
- Adds a sharp, pungent flavour and aroma to the pickling liquid.
- Garlic
- Adds pungent aroma that mellows and deepens during pickling.
The step that matters
Salting and sunning the lemons. Salt must fully penetrate the incisions and fruit so the lemons soften and cure evenly; too little salt or time risks spoilage. The lemons need to stay submerged in their own juice so they do not dry or mould.
Swap the turmeric
The recipe marks turmeric as optional. How well each one fits the dish's main ingredients (lemon, white wine, vinegar, ginger, pepper, mustard, capsicum):
- Tarragonfits about as well
- Thymefits about as well

- Turmericthe original
Fit is the average pairing score against lemon, white wine, vinegar, ginger, pepper, mustard, capsicum. Candidates are from the same food group and used in at least 100 recipes.
