A pressure cooker will save a lot of time when you have a pot roast, corned beef or a whole chicken to cook.

With pot roast, pre-cook in pressure cooker, transfer to a dutch oven and add the vegetables and cook for another 40 minutes, adding vegetables in order of required cooking time.

A whole chicken can be pre-cooked for 20 minutes in pressure cooker, then roasted in an oven, with a major improvement in flavor.

Chicken stock, beef stock and curry base take 40-60 minutes rather than the 3 hours as with conventional cooking methods.
