The company's success in an environment that is not conducive to food operations succeeding is due to a mix of "shrewdness, original thinking, and entrepreneurship." The company originated in Winston-Salem, North Carolina, where it still operates a plant that fills a 23 kg bag with donut mix every seven seconds. It recently opened a new plant in Effingham, Illinois, that fills a bag every three seconds. This second plant allows the company to reduce costs while increasing its output.
