How to Make It
Combine sugar, water, and basil leaves in a small saucepan. Bring to a boil over medium-high, stirring constantly until sugar dissolves. Remove from heat, and cool to room temperature, about 30 minutes. Pour through a fine wire-mesh strainer, pressing solids to remove as much liquid as possible. Discard solids. Store in an airtight container in refrigerator up to 2 weeks.
