Sure, crock-pots are quick and easy to use, but they’re always going to be a little unsightly on your Italian marble countertops. Enter: Mellow. This kitchen gadget may look a little like an empty modern aquarium, but it actually cooks your food using the sous-vide method, which promises a precise temperature for perfect results. Top restaurants use sous-vide all the time, which means that you should too. All you have to do is season your food however you like, put it inside a zip seal bag, drop the bag into the water bath and select the temperature. Once it is done, you can either serve it immediately or pan-sear it a little for some crispiness. If you need more explanation, check out the above video that takes you through the process step-by-step.

Though Mellow doesn’t ship until the spring, you can pre-order it now for only $399 (it will retail for $599).
