Philips Cold and liquid ingredients require more time to heat up than ingredients at room temperature or preheated ingredients. The duration of pressure increase is determined by the quantity in the pot. Larger quantities require more time to reach the indicated pressure, with the duration varying between 1 and 11 minutes. To keep the temperature high in the pot, sauté the ingredients in batches. If you double the amount of ingredients in the recipe, do not double the cooking time. Make sure you do not exceed the maximum filling limit of the pot. When cooking under pressure, it takes a few minutes before you can open the lid. Tableware & Kitchen
