How do you preserve key limes?

Key limes can be preserved using a salting method. This involves layering the limes with salt in a jar, ensuring they are packed tightly and submerged in their own juice.

Here’s a detailed method based on the provided reference:

• Salting Method:
  1. Cut the Limes: Cut the key limes.
  2. Salt the Limes: Sprinkle a teaspoon of salt onto each side of the cut limes.
  3. Pack the Jar: Squish the salted limes into a jar, packing them very tightly.
