... I have a recipe that is my default for PC risotto, you can substitute other stuff for the mushrooms
the basic principle will be the same - in general, less liquid will be needed, and you add it (obviously) at the beginning, then adjust if needed at the end of 7-8 minutes of pressure cooking
here is a link to the recipe I use (it has a non-pressure cooker method too, so you can compare the techniques)
