The Classic is Hawkins largest-selling, most popular range of pressure cookers perhaps because of its attractive combination of features, benefits and price. Each Hawkins Classic features an inside-fitting lid. This design is inherently safer than conventional cookers. Thus Hawkins Classic pressure cooker is pressure-locked for safety like a jetliner door! This range was the first to be introduced by Hawkins and has been kept fresh and current by numerous innovations and improvements over the years. The latest improvement is a 4.06 mm new improved induction base and a superior pressure regulating system that controls pressure to a narrower, more efficient range, reduces sprouting of frothy foods (such as dal) and is easier to insert and remove. The safety valve is located under the lid handle bar so that when it operates the steam is safely deflected downwards. 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, electric, halogen, ceramic and induction cooktops.
