The flame also aids in determining the temperature. Food does not get caught underneath the sealed gas hob burners, making cleanup easy. Heavy pots and pans slide over the continuous grates with ease. To prevent gas leaks, look for a cooktop gas stove that has an automatic re-ignition and shut-off.
