Easy and seasonal; the Backyard Cocktail combines Licor 43 with fresh fruit and Rhubarb Shrub; a delicous component using fresh rhubarb, vinegar, and sugar.
Combine the rhubarb, apple cider vinegar, and granulated sugar in a small saucepan over medium-high heat, stirring as the rhubarb begins to break down.
Bring to boil and then educe heat to low and cook until the rhubarb is completely broken down into strands, about 10 minutes, stirring occasionally.
Remove from heat and pour into a colander or fine mesh strainer lined with a layer of cheesecloth. Stir the mixture gently once or twice to help it strain, but do not press it through the cheesecloth. Discard the solids.
Pour the resulting syrup into a jar and let cool to room temperature.
Store in the refrigerator.
Combine the Licor 43, rhubarb shrub, strawberry juice, and lime juice in a cocktail shaker and shake lightly. Strain into a highball glass over ice. Top with club soda, garnish with a whole strawberry and serve with a straw.
