To Preserve Limes
Ingredients
Directions
Prepare
Select green limes and carefully remove the insides with a penknife.
Soak the limes in a mixture of salt and water for 4 hours.
Remove the limes, wash them, and scald until all salt is gone.
Make the syrup

Skim the syrup and add the limes.
Cook
Boil the limes in water for 20 minutes before adding them to the syrup.
Let the limes boil in the syrup until clear.

What each ingredient does
- Limes
- Provide the fruit, acidity and aroma, and become tender and translucent as they cook in syrup.
- Sugar
- Sweetens the fruit and, in a thick syrup, helps preserve it by drawing out water.
The step that matters
Scald the limes until all salt is gone. Salt has to be fully rinsed and scalded out after soaking, or the preserved limes will taste harsh and salty. Scalding too long, however, can soften the peel and break down the fruit, so timing matters.
