The Gobel N-Stick Obsidian Deep Savarin Ring Mould has a diameter of 240 millimeters and a height of 50 millimeters. This mould is specifically designed for creating deep savarin cakes. The "N-stick" feature likely refers to a non-stick coating or surface treatment, which helps prevent the cake from sticking to the mould, allowing for easy removal and a clean finish. The obsidian material may provide additional heat retention and even baking. This versatile tool is suitable for both professional pastry chefs and home bakers who want to create beautifully shaped savarin cakes with ease.
