Operation How Cook and Hold Works With the optional COOK & HOLD feature, meat is roasted at lower temperatures for longer periods of time. This preserves flavor and tenderness and prevents over drying. There are three phases in cook and hold roasting. D D 225_ 200_ Primary Cooking --- controlled by the COOK & HOLD TIMER. The meat is cooked at a low temperature until approximately 2/3 done. Cooking from Stored Heat --- when the primary cook time expires, the oven automatically switches to HOLD.
Operation General Guidelines for Operating Personnel COOK TIMES AND TEMPERATURES OPERATING TIPS Preheating the oven Pans and Racks Always preheat the oven before baking or roasting. We recommend preheating 50_F (10_C) above the cook temperature to offset the drop in temperature when the doors are opened and cold product is loaded into the oven. Set the thermostat to the cook temperature after the product is loaded. Product or pan height determines how many racks are used. The oven holds up to 9 racks.
