I've been playing with immersion circulator cooking for a year now, and really enjoying it. Up to this point, I've been using ziploc bags and water displacement for cooking. However, I have a developing food safety concern. We have four young kids, and to keep things running smoothly at home I do the cooking for a week at a time on the weekends. MC seemed to be all about the chamber vac; MC@H showed the foodsaver and ziplocs. If I'm cooking with the intent of storing food in the fridge for up to 6 days, how should I be thinking about food safety? Ziploc? Food saver? Chamber? Or are all of these moot points if one is working with a standard home refrigerator rather than a professional model? (That was my theory on why MC@H didn't push the chamber vacs at all.) Thanks!
