Joseph Joseph Silicone 2-in-1Whisk This versatile whisk quickly converts from a standard balloon whisk to a flat whisk with a simple turn of the knob. Use the balloon whisk for aerating batters and whipping cream, then switch to the flat whisk for smooth sauces and batter-free pans. The heat-resistant silicone can withstand temperatures up to 200°C, making it safe for use in pans.
