When buying pots and pans, look for ones that are environmentally safe, can withstand high heat without deteriorating coatings, and react well to temperature changes without damage. Quality cookware should also provide uniform heat distribution without hot spots, retain heat well to reduce energy usage, and be scratch-free and easy to clean for safety and sanitation. Flexible, multi-purpose, and attractively designed pots and pans with a good warranty offer the best value and performance.
