1-Cook with pots and pans that fit the size of the stove:
Using a small pot on a large stove wastes heat and gas. Make sure the size of the pot is right for the burner.
2-Cover the pots when cooking:
Cooking with the lid on reduces cooking time and keeps you warm, which means you’ll use less gas.
3-Take advantage of residual heat:
Turn off the stove a few minutes before the food is ready and allow the residual heat to finish the cooking process.
