Liquefied petroleum gas (LPG) is considered to be a clean burning domestic cooking fuel across the world. The Government of India is promoting use of LPG as cooking fuel among Indian population. Refilling of LPG is not affordable to poor families. It is difficult for the Government to reduce price of LPG cylinders. In such a situation, to make LPG affordable, it is necessary to investigate methods for efficient utilization of LPG.The present work reports results of laboratory experiments conducted to investigate the best combination of pot size for common cooking processes viz. heating of a milk, making of a tea and cooking of a rice. For each type of cooking process, the amount of food items are decided as per need of a family of four members, based on the survey conducted in eighty households. Four types of pots are selected for each type of cooking process and three settings of flame of a smaller burner of domestic LPG stove viz. high, medium and low are used. Each experiment is repeated thrice and uncertainty analysis is conducted using Student's t-test. Based on the experimental results, recommendations are given regarding use of pot size.
