In a professional kitchen you never roast meat directly against the bottom of a pan. The rack lifts the piece from the surface and lets the heat circulate around the whole piece, giving more even cooking, a drier surface and better Maillard reaction on the underside. It is the standard method at The French Laundry, Thomas Keller's restaurant where Hestan is the kitchen equipment manufacturer.
The roasting pan with rack is in 18/10 stainless steel, 35.5x29 cm, part of Hestan Provisions. Suitable for oven-roasted meat, whole chicken and pork loin. Oven-safe, dishwasher-safe.
