The Old Fashioned (in its classic form, a stirred whiskey cocktail with sugar, bitters, and a twist) is a drink whose garnish is critical, relying on the subtle lift of orange oils to balance the strong spirit. But what if you want to up the orange? A proper Old Fashioned would become diluted and unappealing with juice, or with muddled fruit (if you see a bartender muddling up an orange slice and maraschino cherry for your drink, you have our permission to walk away). But using an oleo saccharum as the sweetener brings in even more of those orange oils, for a drink where the citrus flavors are bright and powerful, without any juice to compromise the drink’s strength and clarity.
