Another favorite of Margie’s.
Ingredients:

• 1 cube Sugar
• 1 dash Bitters
• 1 tsp. Water
• 2 oz. Scotch

Instructions:

1. In an old-fashioned glass, muddle Sugar, Water, and Bitters
2. Add scotch and stir.
3. Add a twist of lemon peel and ice.

If you don’t have a muddler (basically a long pestle to grind up sugar in a glass), try using powdered sugar.
