You know, 16 years ago I would have also highly ranked my pressure cooker (mine was not electric). Being able to go from dry beans to meal in less than an hour was fantastic. But when my daughter was born I just surrendered to canned beans out of necessity, so I haven’t used it in years. Actually that’s not true, I just don’t use the lid, the pot is great for making soups, etc.
I have a soy milk maker (Soyajoy, circa 2001), though I haven’t used it in many years. But when I did, I would save the okara and make it into little “meatballs”. I cannot remember the recipe (though I think arrowroot was a key ingredient) but I am pretty sure it came from Bill Shurtleff’s “Book of Tofu”.
