Well, two questions; what cut of meat were you using and how did you season it? The pressure cooker is a pretty intense environment and if it was poultry I can understand why it disintegrated. Tougher cuts of beef or lamb will break down more slowly, but also they are best given a long, slow treatment. I could offer you a recipe for oxtail but it really requires about three hours, not 25 minutes. "No taste", probably not enough salt and aromatics.

What recipe did you use? Was it a recipe designed for a pressure cooker?
I always refer to Lorna Sass who is a pressure cooker guro for any questions. See: http://www.lornasass.com/

I used to have a prestige pressure cooker and always did 25 mins once cone to pressure. I guess I need to try less time.
Will try the website for some recipes, would like to find a nice thick stew as well as a curry

Speed kills. Well, it kills stews anyway.
