According to Steam Rice Master: How Long to Steam, the ideal steaming time for rice is approximately 15 to 20 minutes. This duration ensures that the rice is perfectly cooked, with each grain retaining its shape and texture. The specific time can vary slightly depending on the rice type and the amount being cooked, as well as the type of steamer used.

The reason for this range lies in the need to balance the moisture content and temperature within the rice grains. Rice needs enough steam to cook evenly without becoming mushy or dry. Overcooking can lead to a gummy texture, while undercooking may result in hard, uncooked grains. Data from various rice cooking studies suggest that the optimal temperature for steaming rice is around 212°F (100°C), which is the boiling point of water. This temperature allows for even heat distribution and prevents the rice from sticking together.

For instance, a study published in the Journal of Food Science and Technology found that the best steaming time for long-grain white rice was 18 minutes, while short-grain white rice required 20 minutes. These findings align with the general guidelines provided by Steam Rice Master: How Long to Steam. Additionally, the study emphasized the importance of maintaining a consistent steam flow and temperature throughout the cooking process to achieve the best results.
