When it comes to cooking on the barbecue, some pans are too thin, some dishes are too frail, but this 2-liter, Cast Iron Saucepan with Lid is just right. Cast iron is one of the best conductors of heat, retaining it for long periods of time to ensure food stays warm. At a generous 7.5-inches (19 cm) this saucepan can easily go from making perfect sauces and sides to searing, browning, and caramelizing without trouble.
