Cut limes in thin rounds.

Bring to medium heat. When the sugar is dissolved, add the lime slices.

Step 4

Simmer for 15 minutes, until the white pith looks translucent (thicker slices may take longer).

Place the lime slices on a non-stick baking sheet (like these silicone mats here) or foil.

Step 6

Pour some extra syrup over each slice.

Step 7

Let the limes sit for 1-2 days. Serve.
