Thirst Quenching 'Vinegar Shrubs'

Shrubs are fruit with a yummy vinegar and sugar (think TART, or Brightland to splurge) The mixture is like a syrupy/vinegary that you top with seltzer and a ton of ice for a really sour-sweet cooler. The first time I had a shrub drink was at Botanica in LA and I started making them with plums from the farmer's market and this Food52 recipe.
