pressure cookers and Instant Pots (a popular brand of electric pressure cookers) were quite common in households, especially in the United States and several other countries. The popularity of pressure cookers has been on the rise due to their convenience, time-saving capabilities, and ability to cook a variety of dishes with ease.
Instant Pots, in particular, gained widespread popularity for their versatility and multifunctionality. They can be used as pressure cookers, slow cookers, rice cookers, steamers, sauté pans, and more, making them a popular choice for those seeking a single appliance that can perform multiple cooking tasks.
The exact prevalence of pressure cookers and Instant Pots can vary based on factors such as regional cooking preferences, cultural traditions, and economic conditions. However, by 2021, it was estimated that millions of households in the United States alone owned an Instant Pot or similar electric pressure cooker.
Since my information is not current, I recommend consulting more recent sources like market research reports, surveys, or appliance sales data to get the most up-to-date information on the prevalence of pressure cookers and Instant Pots.
