Stop using too much water in your Instant Pot
The official handbook for the 2018 Instant Pot Duo series states that your pressure cooker needs at least 18 fluid ounces, or slightly more than two cups, of water to operate. The firm has recently reduced this to one cup. Please note that cooking with less water than that is against the manufacturer's instructions and is done at the user's own risk. But you could discover that for certain components, pressure cooking just only a fraction of a cup of water.
A lot of vegetable varieties have a high water content, and a lot of that moisture is lost while cooking. Therefore, while pressure cooking them, you may get away with merely adding a small amount of water to the pot. Although there are many other vegetables with a lot of inherent moisture, the blog specifically mentions mushrooms, zucchini, and soaked beans as falling into this category.
