Elastomoule Mini Muffin Mould Non-Stick 30x20cm: Elastomoule non-stick baking silicone foam moulds require 20% less cooking time and cause product to rise higher. The micro-bubbles in the silicone foam rapidly heat up and immediately transmit the heat to the product being cooked, sealing it and preventing moisture from escaping. For oven cooking or freezing from +300?C to -70?C. Rapid heat transmission. No oil or fat needed. Easy clean and long lasting. Up to 2,500 uses for one mould. Easy turn out without product sticking.
