First of all, let's show some reverence. The Bourbon Old Fashioned is more than 200 years old. It's not just something your grandma drank. It's something her grandma's grandma drank too. Boy, your family really liked booze. Anyway, let's get mixing!
Sugar - 1/2 teaspoon. Use more if you don't care about your teeth.
Angostura Bitters - 3 dashes. Don't get crazy.
Water - 1 Teaspoon
Bourbon - 2 ounces
Garnish - Orange wheel or peel & maraschino cherries
Add the sugar and the bitters to the bottom of a rocks glass.
