In the bottom of your cocktail glass add 1 sugar cube, 1 tsp. water, 1 maraschino cherry, and 1 orange slice. Muddle with a cocktail muddler or the back of a wooden spoon until sugar cube has dissolved, add a few dashes of aromatic bitters to the glass.
Add ice to the glass and pour over 2 ounces of your favorite brandy, stirring to combine.
Top the cocktail with a few ounces of sprite for a brandy old fashioned sweet, squirt for a brandy old fashioned sour, or club soda for a brandy old fashioned press.
Garnish with more cherries, olives, or cocktail mushrooms, however you prefer.
Enjoy immediately.
