Steak is a classic example of where sous vide's low-temperature treatment excels. Easy to overcook on the stove or the grill, a thick steak is hard to screw up in sous vide. Put it in a Ziploc, put the bag in a pot of water heated to the temperature to which you want to cook the steak—129 degrees Fahrenheit for a lovely medium rare—come back in an hour or so, pat it dry, and quickly sear the top and bottom in a hot skillet. Since it's already cooked through, all you're after in this last step is some nice browning. In the Anova oven, I set the temperature, cranked up the steam, put the steak on a sheet pan, slid it into the oven, and went for a run. When I got back, I patted down the ribeye, seared it quickly, and sat down to a perfect steak. It's about as hands-off as good steak gets.
Pork tenderloin, beautifully pink from top to bottom, took the same amount of non-effort. The next day I made a quiche with a pleasing, near-custardy texture.
Behold, the power of steam, a restaurant kitchen superpower (you'll hear chefs refer to it as a "combi" oven) now trickling down to we home-kitchen mortals. While you can certainly do regular oven things in it like bake, convection bake, roast, or broil, in the Anova the big change is steam. For this, there's a large water tank that sits on the right side of the oven and lets out the occasional gurgle.
It's worth noting that it's a countertop behemoth, almost 2 feet wide and 1.5 feet deep.
(I should also disclose that I was paid to moderate panels as part of a 2019 smart home technology conference run by Anova's owner, Electrolux.)
What makes steam special? Its ability to transfer heat. Open a hot, empty oven and stick your hand inside. Bad idea, but you can probably keep it in there for a few seconds with no ill effects. Now imagine doing the same thing over a steamy tray of cauliflower in the same oven. Extra-bad idea, which might net you a quick trip to the ER.
This heat-transfer ability helps some things cook quickly, but it really opens up the door to simplified low-temperature cooking. "Old-fashioned" sous vide is impressive, but those bags are a drag. I love making fried chicken for a crowd on my wife Elisabeth's birthday every (non-Covid) year, using a stack of gallon-sized Ziploc bags, each with a couple pieces of chicken in it. I cook them sous vide, then dunk them in batter, followed by a quick dip in hot oil. Sous vide simplifies the technique considerably: With the bird already cooked, you're just transforming the batter into crunchy goodness in the oil. The end product is stellar, but damn, I feel guilty dumping all of those bags in the trash at the end of the night. (For what it's worth, I've tried reusable bags, but they're a project to clean.) With the Anova oven, you could put the chicken pieces on two 16-by-12 sheet pans and hit Start, skipping the bags altogether. If you've got the room on your countertop and $600 in your pocket, it's a game changer.
