In French, the word 'soufflè' means 'puffed up.' The straight high sides help make it easier for a soufflè to rise. On frozen soufflès, you can increase the height of the dish by wrapping parchment paper around the outside, removing it after the soufflè has set.
Porcelain soufflè dishes are very versatile, and can be used to make baked or cold or frozen souffléès. Their non-porous surface resists stains and is easy to clean. Safe for use in the dishwasher, oven, microwave, broiler and freezer. Lead- and cadmium-free. Thermal and shock resistant.
