Re: Pressure Cookers
I have been a great fan of pressure cookers for 35 years since I inherited my granmother's, which is still going strong. For stocks, soups and pulses they are invaluable not just for speed but for concentrating and the higher heat effects. I now use an induction hob which is much more powerful and controlable than gas or electric. Most of the time I use a German made pressure cooker by MWF.
I am with Syzygies on both Moderniste Cuisine at Home and Heston Blumenthal. One remakable product from a pressure cooker is a sauce for pizza. Salted sliced ripe tomatotoes (let enough jouice run to provide liquid), garlic, a ton of thyme and basil (throw in leaves stalks and all) 10 minutes on high pressure, sieve through mouli legume then boil down rapidly. Adjust seasoning. This is an adaptation from Blumenthal and extracts most of the Umaami which is concentrated in the gel around the tomato seeds.
