Fill two cocktail glasses with ice. Pour one shot of whiskey in each glass. Add 1.5 tablespoons of the brown sugar simple syrup to each glass. Then squeeze half of a lemon into cocktail. Stir then top with lemon rind. Add more simple syrup or more whiskey to your tasting.

Bring the brown sugar and water to a boil then let simmer until the sugar is dissolved. About 10-15 minutes. Let cool then pour into a glass jar or container to use for future cocktails. This may be refrigerated and used over a couple of months.
