Drawing upon more than 50 years of culinary experience, we've designed and developed an exclusive line of nonstick kitchen tools-perfect for use with nonstick cookware. Great for whipping cream and beating egg whites, our professional-quality balloon whisk features heat-resistant silicone-coated wires that quickly aerate ingredients without scratching bakeware or pans. The ergonomically engineered brushed-stainless-steel handle ensures excellent balance and control-and makes the whisk exceptionally comfortable to use. Designed and developed by Williams-Sonoma, and exclusively ours. Stainless-steel wires are coated with durable silicone that's heat-resistant to 500deg.F (260deg.C). Handle is made of heavy-gauge, nonreactive 18/10 stainless steel with a brushed finish. Weighted, ergonomic handle offers optimal balance, comfort and feel. BPA-free and safe for use with nonstick cookware, bakeware and electrics.
