Old Fashioned cocktail is a timeless, classic whiskey cocktail that features your favorite whiskey sweetened with a sugar cube and aromatic orange flavors.
Check the box of your sugar cubes for size. If each cube is 1/2 tsp, use 2 cubes. If you have larger cubes where each one is 1 tsp, then just use 1 sugar cube. Total sugar amount should be 1 tsp.
In an old fashioned glass (also known as lowball or rocks glass), combine sugar cubes, water, and bitters.
Use a flat bottom muddler to muddle together sugar, water, and bitters until sugar is dissolved.
Pour it bourbon whiskey and stir for a few seconds.
Twist orange over the glass to get the oil out and rub the twist over the rim of the glass. (Note: you can discard the orange twist after that or add it to the cocktail. The taste or orange is a bit too much for some so you can discard the twist.)
Add an ice cute to the cocktail, stir a few seconds, and serve.
