I love my pressure cooker because it can transform food in ways that other methods just can't. For example, take tofu. If you use the pressure cooker to cook it, then the water will leach out and you'll be left with tofu that's almost like feta cheese.
People still don't believe me, but it is true.
I also found that it's a great way to make tofu and kimchi. I first fry up some kimchi with some pork belly, add about a 1/4 cup of water, then I set the tofu on top and then pressure cook everything for about 15 minutes. The tofu will have a feta cheese like texture and the kimchi will be soft like saurkraut that has been cooked overnight. It's a very fast, nutritious dinner.
