 It's a miraculous little piece of equipment. You can get them for relatively inexpensively at stores. Many of your stores are online or what have you. You just create a warm water bath. You set a particular temperature. You put the food in a plastic bag, and you submerge it. And it cooks it at this temperature. Yesterday, I needed to do chicken thighs. And you could do chicken thighs in the grill. Just throw them on the grill, and that's fine. But I wanted to really get them infused with some curry flavor. My wife had been craving curry.
