What does it do that is so special?
How is that possible?
What do you need to get started?
Anova Bluetooth Precision Cooker - I went this route because it was cheaper than the wifi model, but the wifi has the advantage of monitoring away from home. The Bluetooth unit can be controlled and monitored via the Anova app ( I use the iOS version) when you are in range. You can set the temperature for cooking, set the timer, and monitor the actual temperature of the water from the app or directly on the Anova unit.
If you have never used a vacuum sealer, they are very easy to use. I had never used one before, but it is as simple as rolling out a bag to the size you want, cutting it (a simple sliding cutter is built in), and then sealing one end, putting in the food, and vacuum sealing the other end. I could not believe how easy it was. They also sell bags that are already sealed on one end and you just put the food in and seal the open end.
We were planning to just use the Foodsaver with the sous vide, but we have also started using it to store food. By vacuum sealing raw meat when you get home from the store, you can extend the life of the meat/veggies by months, and in some cases, up to three years.
Some people will want to sear the food (if desired) once it is finished with the sous vide portion of the cook. I have been putting mine on a gas grill for a few minutes, but you can also finish up with a cast iron skillet, charcoal grill, or maybe a George Foreman grill.
In short, all you really need is a precision cooker, a pot, and a bag.
