What About Lightweight Cast Iron?
Another new option on the market in recent years is lightweight cast iron. Unlike traditional cast-iron pans, lightweight cast-iron pans are made in a metal mold, which allows them to be made thinner. They are also machined or milled to thin them further, and their handles are attached separately with rivets. We tried three lightweight cast-iron skillets, comparing them with our favorite traditional cast-iron skillet in several tests.
All of the pans we tried were indeed lighter than a traditional cast-iron skillet—but that was pretty much their only advantage. All three lightweight pans heated up and cooled down faster than the thicker traditional cast iron. While they were easier to lift and handle, they were also far more reactive to heat changes, which caused them to cook much less evenly, with a distinct tendency to scorch along the outer edges. Overall, lightweight cast-iron skillets proved a disappointment, so they aren’t included in our recommendations.
