Bertram's Cap

Use honey syrup made with 3 parts honey to 1 part water by weight for its listed portion.

Chill a cocktail coupe to prepare it for serving.

Prepare a garnish by slicing an apple, choosing either fresh or dehydrated.

Combine the calvados or your preferred choice of apple brandy with freshly squeezed pink grapefruit juice, honey syrup, a few drops of Bob's Grapefruit Bitters, and a touch of saline solution in a shaker filled with ice.

Shake the mixture vigorously until well-chilled.

Fine strain the cocktail into the pre-chilled coupe glass.

Garnish the drink by floating the apple slice on the surface.
