The Bourbon Ginger Shrub Cocktail is a sweet and spicy drink. Made with a homemade ginger 'drinking vinegar,' this sparkling whiskey, lime and ginger libation is a delightful anytime sipper.
Peel the ginger root with a sharp knife or vegetable peeler. Grate or finely chop. Set aside.
Add water and sugar to a medium saucepan. Cook on medium heat until sugar has dissolved, stirring frequently. Bring to a simmer and add grated ginger. Reduce heat to low. Cook 5 to 10 minutes, until shrub is fragrant. Remove from heat and let cool slightly.
Place a fine mesh strainer over a bowl. Strain the ginger root out of the shrub. Discard the ginger. Stir in apple cider vinegar. Store in an airtight glass jar for up to 6 months. (The vinegar helps to preserve the flavor and will evolve over time.)
For the cocktail, fill a rocks glass with ice. Squeeze a lime wedge into the glass and toss in the spent shell. Add ginger shrub and bourbon. Top with club soda. Garnish with candied ginger and a lime wedge.
