"They Caught Them Sleeping: How Dot Reinvented the Pretzel" by Jeff Kolpack

Dorothy Henke grew up the youngest of six children on a small farm north of Wahpeton, North Dakota, and because of family circumstances was left to essentially work much of the operation as a teenager. Decades later, she was on a first-name basis as Dot with Americans across the country because of a pretzel recipe she invented while living on a farm south of Minot, North Dakota. Dot's pretzels was no accidental discovery, but more a product of her hard-work upbringing combined with her husband Randy, her team of dedicated workers and an inner resolve to get the job done. It's an amazing American success story.
