Make the Syrup:

Combine all syrup ingredients in a small pan over low heat; stir until sugar dissolves.

Increase heat and simmer for 3-5 minutes until syrupy.

Remove from heat, cool to room temperature, strain into a sterile bottle, and chill.

Prepare the Drink:

In a mixing glass, combine all ingredients (except pink prosecco) with 3 ice cubes.

Stir for 30 seconds and strain into a chilled coupe.

Top with pink prosecco, pouring over a bar spoon before serving.
