I rec'd this as a gift. I have made several meat dishes from the receipe book that came with it. Every meal turned out to have tough meat.  Even the beef spare ribs that should melt when the fork touches it turned out tough. Very disappointing. I've spent good money on good meat and didn't get great reviews on the meals.  I used to use my mother's pressure cooker on the stove and every meal was great. I'm wondering if the recepies should be under Low not High.
