An abundance of fruit and produce presents itself in the summer and thus it is the perfect season for making a shrub. Made simply by combining fruit based syrup (think of simple syrup made with fruit juice instead of water) and vinegar, shrubs are a great way of imparting sweet fruit flavors and delicious acidity to a cocktail. In this case, Jamie utilizes a rhubarb shrub that combines beautifully with a citrus forward gin like Martin Miller's.
1 1/2 oz Martin Miller's Gin
3/4 oz rhubarb shrub
2 oz Cava or sparkling white wine
Stir gin and rhubarb shrub with ice.
Pour Cava in to cocktail glass.
Strain gin and shrub mixture over Cava
garnish with lemon peel.
