Boil-in-a-bag has gone high tech. The Anova Precision Cooker attaches to the side of any old kitchen pot to heat water and circulate it evenly, allowing for perfectly moist, tender meals prepared in the sous vide style (as long as food is sealed in an airtight plastic bag). Thanks to Bluetooth connectivity and a companion app for Android and iPhone, chefs can start cooking and monitor water temperature from another room. For $20 more, you can spring for the Wi-Fi-enabled model, which connects to a home network so it can be controlled from afar.
