Cooking during the cooler parts of the day, like early morning or late evening, saves the most LPG during summer as it reduces the need for prolonged burner use to combat the already high ambient temperature.
During summer, the ambient temperature is already high. When you cook during the hottest part of the day, your LPG stove has to work harder to reach the desired cooking temperature. This is because the initial temperature of your ingredients and cookware is already elevated, and the stove needs to expend more energy to overcome this and further increase the temperature for cooking. Cooking during cooler hours, such as early morning or late evening, means the stove doesn't have to fight against as much ambient heat. The initial temperature of your ingredients and cookware will be lower, allowing the stove to reach the desired cooking temperature more quickly and efficiently, thus saving LPG. Furthermore, consider cooking larger batches of food less frequently. This reduces the number of times you need to heat up the stove from cold, which consumes more gas than maintaining a consistent temperature. Planning your meals and cooking efficiently can significantly reduce your LPG consumption during the summer months.
Soaking beans and pulses overnight before cooking can significantly reduce cooking time and, consequently, LPG consumption.
