There's the wild elderberry shrub, and then there's a bottle of Wild Elderberry Shrub ($13) from Wineforest. A shrub, similar to a concentrated syrup, is used to flavor carbonated beverages. Pour a little into soda water for a sweet, berry-flavored drink. Add a bit of gin and mint and you've got yourself a delish cocktail. If you decide to think outside the box, drizzle some over ice cream or pound cake, whip into your creams, or use to brighten your vinaigrette.
