Sous vide machines are pretty good at three things-
Cooking where you need a really precise temperature. Steaks and eggs are good examples. Also think tender chicken, caramelising chocolate, t-bone lamb, custard, fish fillets, parfaits, tender veg (asparagus), and pasteurisation.
Cooking things in marinades and/or their own juices. It retains flavour and keeps them moist.
Low and slow cooking- think stews, tough-cuts, curries and bourguignon. You don't actually need the bags for this (or indeed some of the temperature-specific stuff), just treat it as a large slow cooker, though be careful of things catching if the sides are thin.
Remember when you cook that there are two processes at work; you are breaking down the fibers of the food to make them tender. You are also killing the bacteria in the food to make them safe to eat. Some foods are low risk (clean veggies), some medium risk (steak - potential for harmful bacteria all the way through, but you're almost certainly ok if it's properly seared) and some are high risk (chicken and supermarket pork - you'd be daft to go below 65 C core temperature without the ability to measure & time it).
And if slow-cooking larger joints, it can be a good idea to bring it up to temperature in simmering stock. Bacteria multiplies rapidly between 4 & 50 degrees C, and big joints take a long time to come up to temp. This is a recipe for food poisoning, and having the stuff go rotten in the machine (really, it can happen).
Hi home cooking professionals
I got given a sous-vide thing, and I have no idea what to do with it. I understand I need a vacuum sealer to use it properly. Is there such a thing as reusable plastic bags for a vacuum sealer? Seems pretty wasteful otherwise. What sealer are people using?
Also what should I be cooking in it, apart from steak?
Thanks for any tips
