I make my soup stocks w/the pressure cooker. Very easy & fast. Healthier & cheaper than canned.
There are a zillion recipes out there for pressure cookers. Besides tenderizing tough meat cuts, it cooks veggies super quick without much nutrient loss.
They now have electric pressure cookers which a lot of people love. They are pricey though. I have the old fashioned kind. I think the hardest part is getting used to the timing/cooling method for different items. Once you've made them a few times though, it becomes easy.
