Chef-designed and kitchen-proven with sustainability at the core, Thomas Keller Insignia 0.75 qt. Butter Warmer raises the bar for professional culinary performance with purpose-built cookware focused on exceptional results while remaining eco-friendly. This butter warmer boasts a bespoke handle to rest comfortably in your hand, significantly reduces heat transfer with the thoughtfully placed heat vent, and is seamlessly fastened to the body to eliminate one of the hardest to clean crevices. The triple-bonded stainless steel construction featuring Hestan’s exclusive ProCore aluminum delivers 35% greater heat conductivity. That means faster, more consistent heating, plus faster recovery time to stay in control of temperature and timing. In addition, you’ll find that the butter warmer is wider, not taller, to increase the cooking surface for greater butter, chocolate, and rich dessert sauce and reduction creativity. Durable, innovative sealed rims make this thoughtfully crafted small saucepan 100% dishwasher safe, while purposeful engineering accommodates a wide range of culinary needs including oven and broil safe to 600°F.
