Stove-top griddles are designed to be used on gas stove burners, but they can be used on electric stovetop range cooktops, and they can even be used on grills. \
To use a stovetop griddle on a grill, get the grill started and get it hot before carefully placing the griddle on the grill. Make sure you are wearing oven mitts or using similar hand protection as you are doing this. \
Allow the grill to heat up for five to 10 minutes before you begin cooking on it, the same way you would allow it to heat on your electric stove top range. \
