Joseph Joseph’s folding steamer basket features self-adjusting side, heat-resistant silicone feet and silicone side fins. It is suitable for use in both non-stick and stainless-steel cookware. The design fits a variety of pan sizes with the minimum size being 7”. The fork hook makes it easy to lift out of the pot and it folds for compact storage. If used in a pot with a lid, the pan must be at least 4” deep. Use sufficient water in the pan to allow steam production and do not allow the pan to boil dry or overheat to avoid damage to the product and your pan. Use only in pans with vertical sides and not in frying pans or woks. 4” high x 6 ¼” wide x 6 ¼” deep. Dishwasher safe and BPA free.
