They serve different purposes and the best Pakistani kitchen has both.
Non-stick coated pans are better for eggs, omelettes, parathas, fish, and anything that sticks easily. They require less oil, clean quickly, and are gentler on food that needs careful handling. Always look for PTFE-free and PFOA-free coating.
Granite-coated and marble-coated non-stick surfaces are safer and more durable than basic non-stick coatings. A quality non-stick pan with a 3mm to 4mm base lasts 3 to 5 years with proper care.
Stainless steel pots and pans are better for high heat cooking, long simmering, deep frying, and pressure cooking.
Food-grade stainless steel does not react with acidic ingredients, does not leach chemicals, is rust-resistant and corrosion-resistant, and lasts decades. It handles sustained high heat without warping or degrading - essential for nihari, haleem, paye, and large batch cooking.
For daily Pakistani cooking, use a non-stick pan for breakfast and light cooking and a stainless steel pot or deep fryer for high heat and long simmering tasks.
