The syrup is available through Torani's web site for $6.95 a bottle. According to Torani:
'Bacon enthusiasts will recognize the same savory, meaty flavor as authentic bacon in this salty, sweet syrup. Torani Bacon syrup adds savory bacon flavor to cocktails, lattes, sauces and more. Just add 1/2 - 1 oz. of syrup to a 6-8 oz. beverage, and enjoy this innovative new flavor from Torani.'
Torani kindly supplies recipes for such classic beverages as the Bacon Alexander and the Bacon Bourbon Sour, the latter of which includes bacon syrup, lemon juice, bourbon, and a strip of real bacon as a garnish. Yum!
