Superior Equipment & Supply recently opened a test kitchen inside its facility on Milwaukee’s south side. The company holds cooking classes there from 6:30 to 8 p.m. every Wednesday. Each lesson costs $10 per person, but participants receive $10 certificates to spend at Superior when they attend. Reservations for the classes are recommended because there is a maximum capacity of 25 participants. For a list of chefs and class topics, visit www.superiorequipmentsupply.com or call (414) 671-1200.
