Thank you for your review and for your feedback. We are sorry to hear about your experience. Staub’s textured black matte enamel interior ensures exceptional browning, and heat retention and distribution. Staub’s black matte enamel surface is not non-stick. Using oil will prevent most sticking and ensures exceptional browning. Over time your Staub Braiser will naturally create a non-stick surface on the bottom. The black matt is a "porous" material; It absorbs the "fat" from the cooking and redistributes it when you heat it up again. The more you use it, the more non-stick it will become. Then you will use less and less oil. We hope this helps. If you have any questions, please do not hesitate to reach out to our consumer relations team directly by email at hello@zwillingus.com with your name and contact information.
