You can't use rice cookers to heat oil. The rice cooker 105 degree trips, and the oil temperature is much higher. If you cook chicken wings or other meat with a rice cooker or pressure cooker, you don't need to put oil in it. Some foods, such as grilled ribs, don't even need to put water in the pressure cooker. The water in the food itself is enough. If you want to make chicken wings with cola, you don't need to put oil, put the seasoning away, marinate for more than 30 minutes, and press the button to process it.
