FAQs
Which becomes more nonstick?
Both can become fairly slick with good seasoning and heat control. Results depend on use and maintenance.
Which is better for induction?
Both are typically excellent on induction. A flat base helps performance and burner engagement.
Can I cook acidic foods in them?
Occasional acidic cooking is usually fine, but long acidic simmering can affect seasoning—especially early on.
