7 Steps to make your gas last twice as long

Use an efficient gas stove: For maximum fuel savings, use a gas stove with efficiency more than 72%.
Soaking Dal and Pulses before cooking: Soaking dal and pulses prior to cooking reduces the pressure cooking time required – results in lower fuel consumption.
Use a Pressure Cooker and do not put the vent weight immediately: Place the vent weight (whistle) only when a steady stream of steam begins to emerge. This indicates that the vent tube is not blocked and there is no leakage around the mouth of the cooker.
Use the appropriate burner: Use the small burner for pressure cookers up to 3 litres capacity and the big burner for larger sizes.
Reduce the flame after the first whistle: Once the pressure cooker whistles, reduce the gas flame from high to low or medium. The whistle indicates that the cooker has reached full pressure; continuing to cook on high heat thereafter only leads to wastage of fuel.
Cook by time, not by counting whistles: Follow the recipe and cook for the specified time. Counting whistles is not a reliable way to determine cooking time, as the frequency of whistles can vary depending on the heat level, the size of the cooker, and the nature and quantity of the food being cooked.
Allow Natural Cooling After Cooking: Once the cooking time is over, turn off the gas and allow the pressure cooker to cool naturally. As there is still pressure inside the cooker, the food continues to cook during this stage without consuming any additional gas.

TEST RESULTS

To assess this impact, an exercise was conducted. One standard meal consisting of rice and dal was cooked using three different cooking methods on two 2-burner gas stoves — an ordinary gas stove and a High Efficiency Gas Stove.

For each method, three separate cooking, each of rice and dal were carried out. The weight of gas consumed in each cooking was measured and the average gas consumption was calculated separately for rice and for dal. These two average values were then added together to arrive at the total gas consumption required for cooking one complete meal (rice + dal) using each of the four methods

Quantity of food prepared

900 g of Rice and 350 g of Tuvar Dal was prepared in each method

Gas Consumption for Cooking One Meal (Rice + Dal)

Method	Gas Stove Used	Type of Cooking	Method of Cooking	Gas Consumed (Rice + Dal)
Method 1	Ordinary Gas Stove	Open Pot	Regular Method	126 g
Method 2	Ordinary Gas Stove	Pressure Cooking	Regular Method of Pressure Cooking	95 g
Method 3	High Efficiency Gas Stove	Pressure Cooking	Using 7 Steps of gas saving	57 g

Conclusion

The results show that pressure cooking significantly reduces gas consumption compared to open-pot cooking. Further maximum saving can be achieved by following the 7 steps of gas saving, along with using a High Efficiency Saver Gas Stove.

By adopting Method 3, about 70 g of gas can be saved per cooking compared to the open pot method. And assuming a household cooks twice a day for around 300 days in a year, the annual saving works out to approximately 42,000 g (42 kg) of LPG.

Since a domestic LPG cylinder contains about 14.2 kg of gas, this saving is equivalent to nearly 3 LPG cylinders per household per year.

If such efficient cooking practices are adopted widely, the cumulative savings across millions of households could lead to a substantial reduction in national LPG consumption.
