Ingredients

1 cup sugar 

1 cup water 

2 small Rangpur limes, thinly sliced crosswise 

Preparation

Bring sugar and water to a boil in a small saucepan, stirring to dissolve sugar. Add lime slices and simmer until translucent, about 6 minutes.

Remove from heat; transfer slices to a wire rack set on a rimmed baking sheet and reserve syrup. Let lime slices dry and syrup cool before using, at least 20 minutes.
