Pressure cookers generally require a certain amount of heat to build pressure, so it may not be possible to reach pressure on the lowest heat setting of a stove. However, some pressure cookers are designed to reach pressure more quickly or operate at lower heat levels compared to others.
Electric pressure cookers, such as the Instant Pot, are known for their ability to reach pressure efficiently and effectively. They have built-in heating elements and temperature controls, which allow them to generate and maintain pressure without relying solely on the stove's heat.
If you are specifically looking for a stovetop pressure cooker that can reach pressure on a low heat setting, it's important to note that the specific performance can vary among different models and brands. It's recommended to look for pressure cookers with thick, heat-conductive bases that distribute heat evenly, as they may have better heat retention and efficiency.
Ultimately, it's best to refer to the manufacturer's specifications and customer reviews to find a pressure cooker that meets your desired requirements for reaching pressure on the lowest heat setting.
