UCOOK Duo is a unique combination of Hard Anodised Aluminium body and Stainless Steel lid. Hard Anodised process allows the pressure cooker to absorb the heat faster, thus making it more energy-efficient. It also gives extra strength to the cooker and makes it non-staining and non-reactive with food items. It is made from extremely durable high grade virgin aluminium with hard anodised process from Hindalco. It has a specially formulated food grade rubber gasket, lead free safety valve, and cool touch handles for extra care. This cooker is an attractive combination of features, benefits and price. At UCOOK, we keep innovating our products using customer feedbacks and as a result, we have introduced a Quick Pressure Release system in this cooker. This feature allows the user to release the extra steam with a slide of a finger, rather than using conventional method such as with a spoon or kalchi, which may lead to steam burns. This 5 Litre cooker is ideal for 2 to 4 person meal. You can safely use this pressure cooker for your daily cooking needs.
