Judging the quality of a pan requires a comprehensive assessment of materials, craftsmanship, design details, and other factors, as these directly affect its durability, heat conductivity, user experience, and cooking performance. Here are specific evaluation methods:
Different materials result in significant performance differences in pans, and high-quality materials are the foundation of good quality:
High-quality stainless steel pans typically use "multi-layer composite materials". Use a magnet to test the pan body—if the magnetism is weak or only the bottom is magnetic, it indicates the inner layer may contain high thermal conductivity metals, ensuring more even heat distribution. Pure stainless steel pans have poor heat conductivity, tend to overheat locally, and are of lower quality.
Pay attention to the stainless steel grade: 304 stainless steel is corrosion-resistant, safe, and commonly used for food-grade cookware; 201 stainless steel has poor corrosion resistance, may rust with long-term use, and is not recommended.
High-quality cast iron pans feel heavy (with uniform wall thickness), with a rough surface but no obvious sand holes, cracks, or bulges. Tap the pan lightly—a clear, crisp sound indicates dense texture, while a dull sound may signal internal defects. After seasoning, it should form an even oil film and resist rust.
Focus on the coating quality. High-quality non-stick pans have an even, smooth coating without bubbles, scratches, or missed spots. Choose "food-grade safe coatings", and ensure the coating adheres firmly to the pan body.
Multi-layer coatings are recommended for better wear resistance and longer lifespan.
Pure aluminum pans are prone to deformation and corrosion. High-quality aluminum pans are often "anodized aluminum or "aluminum alloy composite pans". Check for a smooth surface without dents or oxidation spots.
A high-quality pan has a flat bottom (no wobbling when placed on a level surface) and smoothly polished edges. The connection between the bottom and the body should be firm, with no cracks or weak welding.
For pans, "one-piece molding",e.g., die-cast aluminum, cast iron is more durable than welded designs, as it resists leakage or detachment.
The handle must be securely attached to the pan, screwed handles should have tight, non-stripped screws; welded handles should have no slag or gaps. High-quality handles are made of heat-resistant materials, e.g., silicone, and phenolic resin, labeled "heat-resistant ≥200°C" and offer a comfortable grip, curved to fit the palm, balanced weight to prevent tipping when lifting.
Long-handled pans should have a moderate length (about 15-20cm) to avoid overheating near flames; double-handled pans should have a reasonable distance between handles for easy lifting.
A simple test: pour a small amount of oil into a cold pan, heat on low for 1 minute, and observe if the oil smokes evenly. A high-quality pan will have a large, uniform smoking area; uneven or localized smoking indicates poor heat conductivity.
The lid should fit tightly. Good sealing reduces moisture evaporation, ideal for simmering or braising. Glass lids should be transparent, with odor-free, elastic silicone gaskets around the edges.
Non-stick pans should show no coating when wiped with a damp cloth; cast iron pans should maintain an even oil film after repeated use and cleaning, resisting rust and sticking.
Reputable brands often have strict quality control. Look for "food contact safety certifications". Packaging should list materials, heat resistance, and usage instructions.
Avoid unbranded "three-no products", especially for non-stick and stainless steel pans, as poor-quality versions may release harmful substances.
When evaluating the quality of a pan, the key criteria to consider are: safe and durable materials, fine craftsmanship, and performance that matches your cooking needs. For everyday use, focus on "multi-layer composite stainless steel pans," which balance durability and heat conductivity, or opt for "high-quality non-stick pans." If you're looking for something suitable for high-heat stir-frying and long-term use, cast iron pans are an excellent choice.
