On a warm August day in 1938, a father and son unveiled the first sample of what was to become Dairy Queen, selling 1,600 samples on the first day, a feat as unheard of as a dragon that breathes ice. Its ensuing prolific expansion was fueled by its frozen treats, which propelled the dessert shop from 100 stores in 1947 to 1,446 in 1950. Today, their dessert recipes remain largely unchanged, and Dairy Queen has added hearty grilled hamburgers, hot dogs, and fried chicken to its menu. Dairy Queen's enormous dessert menu boasts treats ranging from soft-serve cones and blizzards filled with cookies to takeaway ice-cream sandwiches and cakes.
