Made with only three ingredients, this simple shrub from Cosme’s beverage director, Yana Volfson transforms the attractive and aromatic Japanese herb into something equally special. Adjust the acidity and sweetness to your own taste, and feel free to customize by adding additional spices or fresh herbs along with the shiso. The tart syrup keeps well in the fridge for several weeks. Use it to add flavor, fragrance, and brightness to cocktails and soft drinks, or pack into small bottles for gifting.
