Every year in the weeks leading up to Easter, the four-person staff at Danish Maid Butter Co. starts counting sheep. The Chicago company has made lamb-shaped butter for more than 50 years, moving from wooden molds dropped in cans of ice water to a more modern process. There are other parts of Danish Maid's business that are larger and growing faster, but the two siblings that run the company remain committed to the butter lambs as an important link to both their family legacy and current generations of customers.
