6 ounces (3/4 cup) simple syrup (or maple syrup or honey)
For serving: 16 ounces (2 cups) whiskey of any type
Instructions
Place the lemon juice and simple syrup in a sealed jar and shake. Keeps 1 week in the refrigerator (the flavor is best in first 24 hours, but it’s still good over a week).
For serving, place the sour mix in a pitcher with whiskey with 2 handfuls of ice and pour servings of about 1/2 cup. Or to make single servings, combine 1 3/4 ounces (3 1/2 tablespoons) sour mix with 2 ounces (1/4 cup) whiskey and shake in a cocktail shaker.
