Spiced Blackberry Fizz

1. For shrub, in large jar with lid, combine blackberries, sugar and spices; stir or shake to blend. Allow ingredients to stand overnight at room temperature.

2. Stir vinegar into blackberry mixture; let stand overnight at room temperature. The next day, pour mixture through chinois or fine sieve to remove seeds; reserve strained liquid, which is the shrub.

3. For ginger syrup, in large saucepan over high heat, bring water to a boil. Stir in sugar until dissolved. Add ginger and allow to steep 1 hour.

4. Into chilled, tall glass, pour ginger beer and soda water. In cocktail shaker, shake egg white vigorously for 1 minute. Add ginger syrup, blackberry shrub and lime juice. Fill shaker with ice and shake vigorously 1 minute more.

5. Slowly strain mixture into chilled glass with ginger beer and soda water so it fizzes up. Garnish with a blackberry.
