Why it works: Lemon and turmeric match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 2,192 recipes. Both carry eucalyptol, which smells eucalyptus, herbal. The science ↓
Lemon Pickle
Ingredients
Directions
Prepare the lemons
Grate the peel lightly from the lemons.
Soak the lemons in a mixture of salt and water for 9 days, rubbing them with fresh salt daily.
After 9 days, wipe the lemons with a cloth.
Make the pickle
In a saucepan, combine the lemons, vinegar, mixed spice, and turmeric.
Boil the mixture for 15 minutes.
Transfer the lemons to a jar and pour the pickle over them.
Once cooled, seal the jar tightly with a bladder.
Make the sugared peel
Mix the grated lemon peel with double its weight in sifted sugar for flavoring puddings.

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 of the pickle, with peel and flesh softened by salting and simmering.
- Vinegar
- Acts as the preserving liquid, giving the sharp acidity that keeps the pickle stable.
- Mixed spice
- Adds warm aromatic flavour to the pickle liquid.
- Turmeric
- Adds a yellow colour and earthy flavour to the pickle.
- Sifted sugar
- Sweetens the grated peel used for flavouring puddings.
The step that matters
Boil the mixture for 15 minutes. Boiling must be timed so the spices infuse and the lemons soften without the vinegar evaporating too much or the pickle over-reducing. Sealing only once cooled prevents condensation from diluting the preserving liquid and encouraging spoilage.
Swap the turmeric
How well each one fits the dish's main ingredients (lemon, vinegar, sugar):
- Tarragonfits better
- Peppermintfits better
- Dillfits better
- Turmericthe original
Fit is the average pairing score against lemon, vinegar, sugar. Candidates are from the same food group and used in at least 100 recipes.
