Sous-vide cooking with our new Anova Cooker

Sous-vide cooking with our new Anova Cooker

Sous-vide cooking amounts to putting your food in a sealed plastic bag and immersing it in a temperature controlled water bath for an hour or so. Until recently, sous-vide cookers had cost several hundred dollars, but the latest models are about $100 and suitable for Christmas presents. Our new Anova Nano Precision cooker is just such a device, and we report here on our first experiences with it.

The essence of sous-vide cookery is immersing your food (meat, fish or some vegetables)  in a water bath at just the temperature you want the food to reach. For example, if you want a steak to have an internal temperature of 130˚ F, you put your steak in a vacuum sealed bag in a temperature-controlled water bath at 130˚ F for about an hour. The entire steak will have an internal temperature of 130˚ rather than just the middle. You finish the steak with a quick browning in a pan to give you the outer crust you’d expect.

The Anova cooker is a well-made, compact appliance that you clamp to the side of any fairly deep pot. It comes with minimal documentation (a tiny 5-page leaflet) directing you to download the Anova app for your smart phone.

This app immediately connects to the Anova via Bluetooth, allowing you to manage the settings from your phone. Use of the app is not entirely transparent: you would think that you could adjust the temperature and time from the app, bit you can actually only select times and temperatures associated with various recipes within the app: Beef Poultry, Eggs, Fish and seafood, Lamb, Port and Vegetables (Carrots and Corn only).

Steak

We bought some on-sale prime sirloin steak for our first experiment, placing the seasoned steak into a gallon zip lock bag with some seasonings.

We set the Anova for 130˚ using the app. This took a little fiddling, as it was not obvious at first ow to switch from Rare to Medium Rare. You just swipe right to move to the next temperature setting, but there was no indication on the screen that it was swipe-able. You should bring the water to temperature before putting the meat in. Since you can get tap water at 130˚, this is not too difficult. For high temperatures, you need to use your stove to heat the water, as the Anova takes quite a while to get to higher temperatures.

You slowly lower the bag into the water, letting the water pressure force out the air, and then seal the bag. It should sink in the water if you got most of the air out. We started the cooker, and an hour later had cooked, steak but with a gray exterior. We browned it in a cast-iron pan and then served it.  It was as good as the steak, which in this case was modest, but the cooker worked like a charm.

Chicken Breasts

We also followed the recipe provided with the cooker for chicken breasts.

Nearly all of these are by noted food writer Kenji Lopez-Alt. In those case, we put each of two breast halves in a separate 1 quart zip lock bag with a little oil and a sprig of rosemary and cooked them at 150˚ F for one hour. Then, we browned the chicken skin on a fry pan and deboned the breast easily. We sliced each breast up for serving and ate it with gusto. The breast was perfectly cooked and juicy, unlike nearly all other chicken breast recipes and an simple evening meal. It was great.

Carrots

carrot bag

To cook carrots, you cut them into 1-2 inch pieces, bag them and add a bit of sugar and butter, and seal them for immersion. We simply were not able to get all the air out of the bag because of the irregularity of the carrot pieces. We tried weight the bag by clamping a spoon to it, but the bag leaked and the carrots were not fully cooked. You also have to raise the water bath to 183˚ and this is beat done on the stove. You probably need to invest in a vacuum sealer to do carrots, but since we have a number of recipes for carrots already, this is not that urgent.

It’s not clear how often we’ll use our cooker, but it is very easy to use with the smartphone app and the results are really impressive. We have it in our stove drawer now for easy access.
