*Peach shrub and puree
A shrub is a vinegar-based sweetener that adds a tart acidity to the drink, eliminating the need for citrus. To make the peach shrub, add fresh, sliced peaches in a large pot or bowl. Pour sugar over top. Cover and refrigerate for 12 hours. Remove from fridge and stir to coat any undiluted sugar. Add apple cider vinegar. Stir, cover, and refrigerate for 48 hours more (you can stir during this time to dissolve the sugars). When ready. strain the syrup (peach shrub) into mason jars or airtight containers. Reserve half of the peach slices and puree them in a blender for peach puree. Use the remaining peach slices for garnish.
