KitchenCraft Stainless Steel Non-Stick Porringer 

Designed to cook delicate sauces, the Kitchen Craft Stainless Steel Non-Stick Porringer features a lower pan which envelopes the upper saucepan in water, thereby maintaining an even temperature to prevent the burning or curdling of sauces and custards, and the burning of foods such as scrambled egg. The set includes a 16cm saucepan with a thick encapsulated base, plus a 14cm insert with a rounded bottom, vented toughened glass steam lid, and cool touch riveted side handles.
