The 3.5L Ultra duracook pressure cooker is made of AISI 304 food grade stainless steel and hence ensures rust free healthy food. The high-impact bonded 3 layer composite base enables even distribution of heat through the bottom and aids uniform cooking without any burning or charring. The cooking time is also much less than in other regular cookers. The heat-resistant & heavy solid bakelite handles with twin screws ensures that handles do not become loose. Healthy and fast cooking, durability are good reasons to upgrade to an Ultra duracook stainless steel pressure cooker.
