How would I convert a soup recipe for a pressure cooker?

I can't be bothered re-writing the whole recipe here but it is vegetable broth made with 12 cups of water and the author says to bring it to the boil and simmer for 40 minutes. I just want to know how long I should cook it in the pressure cooker - it is 5.5 litres in size. The broth is supposed to be 9 cups after it's cooked.





Thanks.

Make sure that your ingredients all fit below the pressure cooker's ';maximum fill'; line; overloading a pressure cooker is dangerous.





That said, if you're making a broth, you really can't overcook it. Overcooking vegetables in broth makes them mushy, but you want them to turn to mush because you want all their flavors in the broth.





But in general, a soup that simmers for about 40 minutes on the stove will be done after 5-6 minutes of high pressure cooking. Look for books by Lorna Sass to provide the formulas and recipes you're seeking, because it really does depend on what you're cooking.

If I had to recommend one, it would be ';Great Vegetarian Cooking Under Pressure'; http://tinyurl.com/qc5tqe . It doesn't have any meat recipes, but it has good discussions and charts about soups, dried beans, and grains (rice, bulgur, barley, quinoa), the things pressure cooking make easier. Report Abuse
