By mechanically altering a small batch commercial freezer, Herrell produced an extraordinarily rich, creamy, low-air ice cream.

[1] Herrell was introduced to the Heath candy bar by a friend in the late 1960s and felt that it would make an excellent addition to ice cream.

When he opened his first store, instead of having pre-mixed flavors like chocolate chip, he had his staff mix freshly made ice cream with candy or other confections based upon customer requests.

The custom-blended flavors proved to be highly desired by customers, and Herrell sold out of ice cream on his first day open.

[5] After this expired in 1980, he opened Herrell's Ice Cream, bringing with him all of the original recipes and techniques he used at Steve's.
