Purple Ribbon Beef will be at the Clear Lake Farmers Market in the parking lot at the Surf Ballroom in Clear Lake. Shoppers can browse locally grown produce, fresh baked treats, and handcrafted goods, then pick up offerings from Purple Ribbon Beef such as high quality dry-aged cuts, convenient meal options, snack sticks and jerky, tallow-based items, and other Iowa-made specialties. Advance ordering is available for fast pickup at the booth. The market continues regardless of weather, so bringing cash and reusable bags is helpful and planning for conditions makes the visit easier. Take in the lakeside atmosphere while supporting local growers, makers, and producers.
