Peach Pit Vinegar

The pits of peaches and nectarines have a flavor reminiscent of bitter almond. Soak the pits (especially those that still have flesh clinging to them) in apple cider vinegar to impart that flavor, then use anywhere you would vinegar, but I like it best as a shrub. Take ½ cup [120 ml] of peach pit vinegar and ½ cup [100 g] of brown sugar, shake to dissolve, then use as the base for a spritz, either with just soda water or soda water and bourbon. Thanks to Emily Spurlin for teaching me so much and especially for this technique.
