Why it works: Lime and sugar are a kitchen classic. They rank in the top 29% of all ingredient pairs, and cooks put them together in 3,332 recipes. Both carry 1-penten-3-one, which smells fish, pungent. The science ↓
Lime Preserves
Ingredients
Directions
Prepare the limes
Lay limes in a saltwater solution strong enough to float an egg, covering them until warm weather ends.
Cut limes to remove all seeds.
Soak the cut limes in cold water for one day, changing the water often to remove salt.
Boil the limes in water with 1 teaspoon of soda per 6 quarts of water until tender enough to pierce with a straw.
Soak the boiled limes again in cold water for one day, changing the water often.
Make the syrup and preserve
For each pound of fruit, use 2.5 pounds of white sugar and 3 pints of water.
Boil the syrup for 15 minutes.
Add the fruit to the syrup and cook for 5 minutes.
Remove the fruit and place it in jars.
Cook the syrup for an additional 15 minutes before pouring it over the fruit.

What each ingredient does
- Limes
- Provide the fruit that is softened and preserved, giving the preserve its main flavor and body.
- Coarse sea salt
- Draws water out of the limes during soaking, helping to firm the fruit and reduce bitterness.
- Soda
- Alkaline boiling water softens the lime peel so it becomes tender enough to pierce.
- White sugar
- Forms a thick syrup that sweetens the fruit and preserves it by drawing out moisture.
The step that matters
Boiling the limes until tender. Boiling with soda must be carried only until the peel is tender enough to pierce with a straw. Overcooking breaks the fruit down into mush, while undercooking leaves the peel tough and bitter.
