I remember the first time I had this cocktail. Ms. Jane Elkins made it for me at Louis 649 several years ago. I'm not sure I've had one since. I've got some allspice dram at home (made by my mom!) and have been trying to think of ways to put it to good use. This came to mind.
Lion's Tail
2 ounces bourbon
1/2 ounce fresh lime juice
1/2 ounce allspice dram
1-2 dashes Angostura bitters
1/2 teaspoon simple syrup
Shake with ice and strain into a cocktail glass.
