For anyone not in the know, America’s Test Kitchen is a truly amazing institution.
They apply an almost scientific rigour to cooking, testing not only recipes but ingredients as well, and also testing the implements to prepare dishes with. As they put it “Our mission is simple: to develop the absolute best recipes for all of your favorite foods. To do this, we test each recipe 30, 40, sometimes as many as 70 times, until we arrive at the combination of ingredients, technique, temperature, cooking time, and equipment that yields the best, most-foolproof recipe.”
They did a test of something important that goes beyond cookery - fire extinguishers. Worth a look.
