In order to cook food using such a cooker, while maintaining the heating elements in parallel, food ingredients and water to be cooked are put in the inside, and a separate ignition rod is ignited, and the ignition ignition rod is placed on the lower part of the heating element. The gas is ignited by opening the valve coupled to the gas supply pipe after being positioned near the installed burner, so that food can be cooked.
