Pressure cookers are used for cooking food more quickly than conventional cooking methods, which also saves energy. Pressure is created initially by boiling a liquid such as water or broth inside the closed pressure cooker. The trapped steam increases the internal pressure and temperature. After use, the pressure is slowly released so that the vessel can be safely opened. Pressure cooking can be used for quick simulation of the effects of long braising or simmering. Almost any food which can be cooked in steam or water-based liquids can be cooked in a pressure cooker.</br><br/>http://www.amazon.com/gp/product/B00Q0SR2HK
