The Hawkins 3 Litre Inner Lid Pressure Cooker is made from food-grade, 18/8, non-magnetic, superior stainless steel (AISI Grade 304). It features an extra-thick sandwich bottom that heats evenly and stays flat always, making it safe for light and deep frying before pressure cooking. The pressure cooker is designed with a unique pressure-locked safety lid that ensures the lid cannot be opened until the pressure has fallen to a safe level. It also includes an improved pressure regulator that saves more fuel and an automatic safety valve positioned to deflect steam and food safely downwards. The gasket lasts longer due to minimal exposure to food acids and the fixed sturdy pivot assists in locking the lid securely.
