Smoky Irish Wolfhound

Preheat an outdoor grill for high heat.

Cut grapefruit in half crosswise. Cut a slice from one of the halves, about 1/4 inch thick. Sprinkle both sides of the grapefruit slice with smoked salt.

Place grapefruit halves cut-side down on hot grill, along with grapefruit slice. Grill until slightly charred and grill marks appear, flipping the slice halfway through, 2 to 3 minutes. Remove from grill and let cool. Squeeze the juice from both halves and set aside. Cut grapefruit slice into 6 wedges.

Add 2 slices of ginger and 4 wedges of sliced grapefruit to a cocktail shaker. Use a muddler to slightly crush the crystallized ginger and grapefruit. Fill the shaker with ice cubes, whiskey, and 3 fluid ounces of grapefruit juice. Cover and shake until chilled, 15 to 20 seconds.

Fill 2 rocks glasses with crushed ice and divide cocktail amongst the 2 glasses. Top each glass with 1 fluid ounce of ginger beer. Garnish with remaining grapefruit wedges and crystallized ginger.
