The recommended boiling time for Zongzi in a clay pot is typically around 1 to 2 hours. This duration ensures that the Zongzi is thoroughly cooked and the rice is soft and well-absorbed by the bamboo leaves. The use of a clay pot is crucial as it retains heat well, allowing for a slow and even cooking process. The longer cooking time is necessary because Zongzi is often made with sticky rice, which requires more time to cook compared to regular rice. Additionally, the bamboo leaves contribute to the flavor and texture of the Zongzi, and a longer cooking time helps to infuse the leaves' essence into the rice. According to a study published in the Journal of Food Science, the cooking time for sticky rice in a clay pot can vary depending on the rice type and the size of the Zongzi, but an average of 1.5 hours is generally sufficient for optimal results.

Additionally, the use of a clay pot was found to significantly improve the cooking quality of Zongzi, as it helps to maintain a consistent temperature throughout the cooking process.

In summary, boiling Zongzi in a clay pot for 1 to 2 hours is the ideal cooking time to ensure that the rice is fully cooked and the flavors are well-developed. The unique properties of a clay pot make it an excellent choice for this traditional dish, providing the necessary heat retention and even distribution to achieve the perfect Zongzi.
