Blueberry Shrub

1. 1

   Place the blueberries in a nonmetallic container. Add the vinegar. Cover tightly and refrigerate for at least 3 days.

2. 2

   Pour the vinegar-marinated blueberries into a sieve over a bowl; press the berries to release all their juice. Discard the solids.

3. 3

   Pour the blueberry liquid into a medium saucepan. Add the sugar and boil for 3 minutes, stirring occasionally. Remove from the heat and let cool. Pour the sweetened blueberry liquid into a small container and chill.

4. 4

   To make each drink, add 1/4 cup blueberry concentrate to a medium cocktail glass filled with ice and add 1 cup cold water. Garnish, if desired.
