Sous Vide for $20 Answered
Sous vide is a cool way of cooking foods at low temperatures for a long time that makes the flavors more intense as a result. Even the cheapest setup for this is about $150 if you already have a rice cooker or crock pot lying around. Serious Eats has explored this territory before with success and now has a method for doing this with nothing but a simple beer cooler and some ziploc bags.
To do it you need to fill up your cooler with water a couple degrees higher than your target temperature. Then just drop in ziploc bags with your meat inside. Wait an hour or two and voila! Cheap sous vide.
This method only works for a couple hours so it won't help you cook your ribs for 48 hours, but but does give you an introduction to the technique and help you decide if you want to go for the full setup.
