This is truly an Amazing way to cook.. I watched every season of Top Chef and this is where I first heard of Sous Vide, lol.. I learned from that show that you can cook just about anything for however long and it will always come out they way you intended it to cook ! So I have always been interested in trying this out, as I love Fish and Steak, but I am not always consistent on especially my steak being medium rare ! So I have been doing a lot of research on these devices and went ahead and made the leap to the RioRand. I seen some that had Wifi and Bluetooth,lol.. I knew that is something I would really ever use. I received my Immersion Cooker in two days, I opened it up, and I couldn't believe how sturdy and much bigger than I had imagined ! It comes with an easy to follow instruction manual, and a recipe book, as well as a meat tenderizer! So I have been playing with my new gadget and have learned a few things, one being it is very quiet, it heats up the water very quickly, no need to buy a vacuum sealer like I thought, zip lock bags are just fine ! Also you are to heat the water to the temp before putting your food in when you plan to user a timer, lol... Its been a lot of fun, I will say that your steak doesn't look a pretty color, but its at the perfect doneness and you just sear it on both sides in a frying pan, and wow, its dynamite !!
