How Does copper vs stainless steel Cookware Work?

Cooking enthusiasts often find themselves at a crossroads when choosing the perfect cookware: copper or stainless steel? Both materials have their own set of advantages and drawbacks. To help illuminate the differences and make a more informed decision, we've gathered insights from industry experts and seasoned home cooks.

Heat Conductivity

Copper is often lauded for its superior heat conductivity. Chef Thomas Keller, a Michelin-starred professional, states that copper cookware distributes heat evenly and quickly, which is crucial for achieving precise culinary results. On the contrary, stainless steel doesn't conduct heat as well as copper, but its multi-layered construction (often with an aluminum or copper core) compensates for this drawback. According to the renowned All-Clad brand, stainless steel’s layered construction can rival copper in heat distribution while offering durability.

Durability and Maintenance

One of the significant advantages of stainless steel is its durability. It doesn’t rust, corrode, or tarnish. According to a report from Consumer Reports, stainless steel is virtually indestructible with proper care. Copper, while visually appealing, requires more maintenance to prevent tarnishing and to maintain its appearance. Chef Julia Child famously endorsed copper cookware but admitted that it requires regular polishing to stay in top condition.

Surface and Reactivity

Stainless steel is non-reactive, which means it won’t interfere with the taste and color of acidic or alkaline foods. On the other hand, copper is highly reactive. According to the Institute of Culinary Education, cooking with copper necessitates a tin or stainless steel lining to avoid metal leaching into food, which could cause health issues.

Weight and Handle Comfort

Stainless steel cookware is generally heavier than copper, offering stability but sometimes at the cost of maneuverability. Copper, being lighter, is easier to handle but requires attention due to its heat conductivity. Chef Alton Brown emphasizes using cookware that feels comfortable and balanced, and while some home cooks may prefer the heft of stainless steel for tasks like searing meat, others might appreciate copper's lightweight nature for sautéing.

Effect on Cooking Time and Energy Efficiency

Professional chef Gordon Ramsay highlights that copper’s excellent heat conductivity can save cooking time and energy. Faster heat-up times mean less energy consumption. In contrast, stainless steel, especially varieties with a thick base, might take longer to heat but retains heat more efficiently, providing consistent cooking temperatures.

Price Considerations

Generally, copper cookware tends to be more expensive than stainless steel due to its superior heat conductivity and aesthetic appeal. However, when considering long-term use and durability, stainless steel offers excellent value. According to a survey by Cook’s Illustrated, many professional kitchens prefer investing in high-quality stainless steel due to its longevity and versatility.
