Pressure cookers are great additions to modern kitchens, particularly for those individuals that like to prepare their own food without all the stress associated with other cooking techniques. Pressure cookers are the best tools to use when you want to prepare tasty and nutritious meals and you do not necessarily have a lot of free time to spare.
However, before you can start using pressure cookers, it is important that you educate yourself about these gadgets as much as possible to avoid using them incorrectly. One of the precautions that you should maintain when using pressure cookers is to pay attention to the hissing or whistling sound produced by some cookers.
Why Pressure Cooker Whistles and Not Whistling?
Why does your pressure cooker whistle?
Pressure cookers are used all over the world, which means that pressure cooker designs vary from place to place. For instance, the pressure cookers that are used in India and parts of Asia and Europe are quite different from the pressure cookers used in the American market. Most pressure cookers available in the American market come with a spring valve.
These types of pressure cookers are designed to regulate the pressure using a weight. The weight sits on top of the vent until the maximum pressure is inside the pot is reached. The weight then lifts once the pressure is attained so that any extra pressure can be released. Some pressure cookers lids are also created with mechanisms to release steam so that a safe level of pressure can be maintained at all times.
In these pressure cookers, when pressure builds to excessive levels, the safety valves within the lid open to release excess pressure which is what results in the rattling or hissing sound. In most scenarios, electric pressure cookers are the quietest because they are equipped with systems designed to allow them to better regulate pressure. However, even electric pressure cookers do produce some sounds, although it might sound like hissing more than whistling.
Why is your pressure cooker not whistling?
There are several reasons why pressure cookers produce a hissing sound. For one, a pressure cooker will produce a hissing sound if the lid has not been sealed properly or if the pressure release valve is left open accidentally. If this is the case, the issue must be dealt with and corrected immediately to so that pressure within the pot can be maintained and so that food can cook through evenly.
A hissing sound may also be produced if the pressure is too high. When the pressure is excessively high, the lid will produce a hissing sound to alert the cook that the pressure inside the pot needs to be brought down. When this is the case, the hissing sound can be stopped by reducing the heat, which should stop the pressure cooker from hissing like a siren.
If your pressure cooker does not produce any whistling sound once the cooking process is complete, you should try shaking the valve slightly to release any blockages that may be obstructing the pressure from being released.
