Forget those agonisingly sweet, candy-tasting limoncellos you might know. This should be fragrant, slightly numbing and tingling, and quite bitter. Kind of like Campari, but with less sugar. It’s a refreshing drink alone, with soda water, or in cocktails. Pompelmocello and Buddhacello are my favourite of the citrus infusions, by a long way. This is based on a recipe from Burning Pasta.
