Combine everything but Prosecco in a cocktail shaker with ice. Shake for 5 seconds, strain into a champagne flute and top with Prosecco. Using a vegetable peeler, remove a strip of peel from an orange. Express the oil from the orange peel over the cocktail and twist over the rim of the glass as a garnish.

Additional Tip
This cocktail makes an excellent (Mother’s Day) brunch cocktail. For a larger batch, multiply the ingredients each by 10 and combine in a carafe or pitcher. Since you won’t be shaking with ice, add a small amount of water for dilution if desired. Stir to combine and refrigerate until cold.
