Blue BMW

Chill the cocktail coupe by placing it in the freezer or filling it with ice water until ready to use.

Add the cognac, blue curaçao, amaro, sweet vermouth, and half-and-half to a cocktail shaker.

Add a few dashes of cranberry bitters to the mixture.

Fill the shaker with ice and secure the lid tightly.

Shake vigorously until the mixture is well-chilled and frothy.

Remove the ice or water from the frozen coupe glass, if used for chilling.

Strain the shaken cocktail into the prepared coupe glass, allowing the vibrant, dark green concoction to settle beautifully.
