1-1/2 fl. oz. (3 Tbs.) gin, preferably Bluecoat American Dry
1/2 fl. oz. (1 Tbs.) limoncello, preferably Averna Limoni di Sicilia
Prepare a gas or charcoal grill fire for direct cooking over medium-high (500°F) heat. Grill the thyme sprigs until fragrant and lightly charred, about 15 seconds. In a mixing glass or cocktail shaker, gently muddle the grilled thyme with the lime juice. Add the gin and limoncello and fill the shaker with ice. Stir well. Strain into a chilled rocks glass filled with fresh ice, garnish with thyme, and serve.
