Definitely try the shrubs...
I've been going nuts with them. It's easy. 1 part each of sugar, fruit, and vinegar. After several weeks, strain the fruit out.
This was the old-timey way the pioneers preserved fruit juices for winter use to flavor cooking and drinks. It was the citrus "sweet and sour" in punches and drinks when lemons weren't available, the vinegar subbing for the citrus and the fruit giving a whole new flavor dimension.
One of my favorites so far: Cherry Disposition
I re-created this at home after tasting it at one of the downtown restaurants serving up craft cocktails. Shrubs are in big time.
Cherry Disposition
3 tablespoons blackcherry shrub
3 white peppercorns, crushed, or equivalent of freshly ground
2 oz. Hendrick's Gin
In a shaker filled with ice, combine, shake for at least 30 seconds, serve neat in chilled/frozen stemmed-cocktail/gimlet glass.
AMAZING!!!
I've also got a plum shrub going that is out of this world. Also have blueberry, orange, and peach in process.
