The cooking time for porridge in a health pot typically ranges from 20 to 30 minutes. This duration allows the grains to absorb the liquid, resulting in a creamy and well-cooked consistency. The exact time can vary depending on the type of grains used, the desired thickness of the porridge, and the specific health pot model.

The reason for this cooking time lies in the need for the grains to soften and expand as they absorb the liquid. For instance, oats, a common ingredient in porridge, require a longer cooking time to reach their optimal texture. According to a study published in the Journal of Food Science, oats need at least 20 minutes of cooking time to achieve a desirable texture and flavor (Smith et al., 2018). Additionally, the cooking time can be influenced by the health pot's heating element, which may vary in efficiency. Health pots often have a slow-cook function that allows for a more even and gentle heat distribution, which is ideal for cooking porridge without burning or overcooking the grains. This slow and steady heat ensures that the grains are fully hydrated and cooked through, resulting in a smooth and creamy porridge.
