In a large glass jar or bowl, combine the figs, huckleberries, and sugar. Mash lightly, cover tightly, and let sit for 24 hours, stirring occasionally to dissolve the sugar. After 24 hours, strain the mixture through a fine-mesh sieve, pressing on the solids to extract the liquid syrup. (The solids are good stirred into plain yogurt, or tossed with more fresh fruit and baked into a crisp.) Stir the vinegar into the syrup, pour the syrup into a jar, and store in the refrigerator. The shrub will keep for up to at least a month, and probably longer. To serve, mix a tablespoon or two of syrup into a glass of ice and fizzy water, squeeze in a lime wedge, stir, and serve.
If you can't find huckleberries, blackberries or wild blueberries make good substitutes.I like the clean taste of sugar here, but feel free to try this with 1/2 cup honey or 2/3 cup grade A maple syrup in its place.Nutritional values are based on one of eight drinks.
