Frequently asked
Is cast iron difficult to maintain?
Less than its reputation suggests. After cooking: rinse while warm, dry completely, apply a thin layer of oil, store dry. Don't soak in water. Rust if left wet is surface-level and reversible — just scrub off and re-season.
Is non-stick PTFE (Teflon) safe?
Yes at normal cooking temperatures. PTFE starts to degrade above 260°C — overheating a non-stick pan on a very high burner (empty) is the risk. At normal cooking temperatures (180-220°C), PTFE is stable and inert. If the coating is scratched and flaking, replace the pan.
