Ingredients

　　1 cup sugar

　　2 Key limes (about 1 ounce each), very thinly sliced into rounds

　　In a 10-inch sauté pan, bring sugar and 1 cup water to a boil, stirring constantly until sugar dissolves. Reduce heat to a gentle simmer. Add lime slices in a single layer, arranging them so they do not overlap. Cook until white pith is translucent, 30 to 40 minutes, turning slices two or three times during cooking. Using a slotted spatula, carefully transfer slices to a wire rack to cool completely before using.
