The proper utensils which can be used for microwave cooking are those that have a statement printed “microwave safe” at the base of the utensils. This means these utensils are certified and safe for use in microwave cooking. Utensils without “microwave safe” should be checked to ensure they are suitable. Place the utensils in the microwave along with a glass filled up with half full of water. Heat up with maximum power or “High” setting for one minute. If the item is hot, you should not use it. If it is just slightly warm, you can use it for reheating but not for cooking purpose. If the item is maintained at room temperature, it is suitable for microwave cooking. Metal utensils and utensils with metallic trim should not be used in the microwave, unless specifically recommended for microwave use.
