Yes! You are really concerned about your LPG consumption. Be it financial or environmental, the concern is genuine. Reduce wastage while maintaining efficiency is the only solution left to you in order to go hand in hand with an LPG living.
With a little bit of planning and a pinch of patience, you can sprout miracles upon your monthly budget, even if you are zero-bothered of, say, thermodynamics.
The most efficient way is to actually reduce the amount of gas you use as well as waste.
So, before turn the burner on, make sure that all the ingredients for the cooking are ready at hand. Clean and wipe the pan well before putting it atop the burner. Try to use shiner-surfaced pans rather than dull black ones. These preparations would save a lot of unnecessary wastage of LPG.
Even though health specialists advocate for clay utensils, to save fuel it is better to go metal as they are good conductors and hence require less amount of heat energy.
Choose your pan size so as not to let the flame extend beyond the pan, to avoid wastage of heat to outside the pan. Keep the lids closed to cook the stuff by the pressure formed inside due to heating. Trap the evolved steam inside. Often, a pressure cooker will save you in this matter.Add only the required amount of water and never a drop plus. It may steal your gas and time, if not.
Once the boiling point of the liquid is reached, lower the flame, as it is impossible to heat beyond 100 degree Celsius which is already there inside. So just maintain the same temperature keeping a small flame, to cook naturally. Remember, smaller the flame, lesser the gas burned.
For vegetables, overcooking will have its bad effect of evaporating the needed nutrients. For leafy green, it requires zero cooking. Just spread it on the hot food stuff.
Cook in large quantity at a single stretch. Then you need only a toast or a microwave oven which are regulators of your LPG consumption. Thaw frozen foods completely before cooking. Likewise, keep your cooked food stuff in thermo containers to avoid re-heating.
Check for gas leaks. Make sure that the flame is colorless or blue. Yellow flame is the indicator of incomplete burning. Call the technician in time to avoid further loss of gas.
So, do not compromise your cuisine at a shortage of LPG.
