Miss Mary Handi pressure cooker features a Curved Body for easy stirring, easy removal of food, better visibility of food. It has a 3.25 mm thick metal base which is stronger, safer, hygienic. Each Miss Mary cooker is tested to be leak-proof. It has an improved vent weight (Whistle) which is more efficient, causes less dal sprouting, cooks faster and saves fuel. Each Miss Mary Handi features an inside-fitting lid. This design is inherently safer than conventional cookers. Thus it is pressure-locked for safety – like a jetliner door! The safety valve is located under the lid handle bar so that when it operates the steam is safely deflected downwards. The gasket has minimum exposure to steam inside the cooker, does not rub every time the product is opened and closed – so lasts longer. Stay-cool handles. Fixed sturdy pivot does not put pressure on the plastic handles as it is a part of the metal handle itself. Thus handles last longer. Recommended for use on gas stoves.
