Cooking Methods Microwave Cooking Microwave cooking uses high frequency energy waves to heat the food. When cooking, microwave energy causes food molecules to move rapidly. This rapid movement between the food molecules creates heat, which cooks the food. Microwaves cook moist food and foods of varying fat content more quickly. Convection Cooking Convection cooking utilizes both a convection element and fan to evenly distribute heated air throughout the oven cavity.
Cookware Suggestions What Should You Consider in Cookware? Cooking method used determines the cookware that can be used. To simplify choices, use cookware that is approved for all three cooking methods: microwave, convection and combination. Select Avoid Heat resistant glass Non-heat resistant glass Ceramics or china Metal trimmed ceramics or china Pyrex Metal cookware Heat resistant Teflon utensils, such as spatulas. Metal cooking utensils.
Microwave Cooking Recall This feature enables you to repeat the previous cooking cycle without having to reprogram the oven. To use simply press CANCEL/STOP and then RECALL. What is stage cooking? Stage cooking enables different cooking cycles, or stages, to be used consecutively without repeated input from the user. Stage cooking can be set to to defrost food initially, then cook it, and then keep the food warm until serving time.
Microwave Cooking (cont’d) Auto Defrost Four different preset defrost settings are available depending on food being defrosted. For added convenience, a built-in tone reminds you to check, turn over, separate or rearrange food during the defrost cycle. 1. Press CANCEL/STOP 2. Press DEFROST AUTO/TIME once. • MEAT TOUCH 1 POULTRY TOUCH 2 FISH TOUCH 3 BREAD TOUCH 4 scrolls through display. 3. Press appropriate digit pad. • ENTER WEIGHT scrolls through display. 4. Enter weight using digit touchpads.
Convection Cooking ! CAUTION To avoid risk of burns, handle utensils, racks, and door with care. Allow oven, utensils, and racks to cool before cleaning. Oven, utensils, and racks, become hot during operation. To operate the oven for convection cooking only, you can use auto pads or manual time entry. The following instructions are for convection cooking only. For combination cooking, see that section.
Care and Cleaning Clean oven frequently to maximize oven life, performance, and efficiency. A dirty oven cooks inefficiently because moisture, spills, and grease absorb convection and microwave energy. ! WARNING To avoid electrical shock which can cause severe personal injury or death, unplug power cord or open circuit breaker to oven before cleaning oven. ! CAUTION To prevent burns, handle utensils, racks, and door with care. Allow oven, utensils, racks to cool before cleaning.
