My Mother has had the old fashioned type of Prestige pressure cooker for many years, which I watched her use throughout my childhood. On a whim after watching Jamie Oliver use a similar style pressure cooker to this one, to make one of his soups. I thought this must be a buy for me. Have just used to make a mound of potatoes for a cottage pie. Then went on to use to cook a selection of vegetables, carrots, baby corn, french beans, sugarsnaps and courgettes all in one go. Wow, no steamed out kitchen, one pot washing up. Found this very easy to use. Read instructions carefully, must get cooker up to pressure before reducing heat. I think cooking times are a guide line and cook to own taste, this comes with practice and use.
