Famous for its small, square hamburgers, the Krystal Company will debut a maple bourbon milkshake Sunday as part of a menu expansion of "playfully Southern" recipes, the Chattanooga Times Free Press reported.

The temporary menu item will be introduced at most of the fast-food chain’s 350 restaurants. Despite its name, there will be no alcohol in the shake -- just real milk and soft-serve ice cream.
"The maple bourbon sauce uses pure, grade A maple syrup sourced from both the United States and Canada," Brandon Freeman, Krystal's senior manager for culinary innovation, told the Times Free Press. "I'd describe the flavors of bourbon as caramel, oak, charred oak, toffee and vanilla."
Company president Paul Macaluso said limited-time offers like the bourbon-flavored milkshakes can boost sales at Krystal by as much as 40 percent.
"We know that our guests crave new and vibrant flavors and have come to expect our menu innovation to be playfully Southern," Macaluso told the Times Free Press. "Our new maple bourbon shake over-delivers on that expectation and is absolutely delicious."
The milkshake is an attempt by Krystal to reverse two years of lagging sales, the newspaper reported. The company introduced pimento cheese bites and frozen Lemonhead slushies during a two-month summer promotion that ended in August.
Krystal opened its first restaurant in downtown Chattanooga in 1932 and claims to be the second-oldest fast-food chain. White Castle is the oldest, founded in 1921.
