Sous Vide Corned Beef for St. Patrick's Day.

I've been having fun laying with my Nomiku immersion circulator, so I decided to put it to good use for our traditional St. Patrick's day meal.  We usually cook the corned beef, the centerpiece of the meal, in the crockpot for about 10 hours.  The result is very tasty, but leaves something to be desired in the texture.  It is usually falling apart and kind of stringy by the time we get home, or if we cook at a lower temperature it may still be tough and dry.  This year I decided to cook the corned beef sous vide.

There are several recommended time/temp combinations for corned beef on the internet, from 82C for 10 hours to 58C for 72 hours.  I decided to cook ours for 48 hours at 64C, which fit the best in to my schedule. Because I had a rebate check for Costco we picked up a corned beef (Sy Ginsberg brand) there along with a second component of my plan...a case of guinness.

Corned beef in water bath with frozen Guinness/spice puck still visible.

The first step was to make a guinnesscicle, I poured about 2/3 cup of Guinness in to a plastic container, added a tablespoon of corned beef spices I bought from The Spice House, sealed it up and put it in the freezer.  The next day it was frozen solid and ready to use.  I filed up my 12" x 18" x 9" polycarbonate box with hot water from the tap, the minimum and maximum levels are written in Sharpie on the box so I filled it to about an inch below the max level and attached my Nomiku.  After touching the screen to turn it on I set the temperature to 64C and left it to heat up.  Meanwhile I removed the corned beef from its packaging and rinsed off as much of the salty brine as possible.  Because we would not be doing the traditional cooking method of simmering in lots of liquid I wanted to eliminate as much of the salt as possible.  Once it was rinsed and patted dry I put the Guinnesscicle in a vacuum bag along with the corned beef and sealed it up.  In the picture above you can see the still frozen Guinness in the bag.  The bag was put in to the bath and the waiting began.

Nomiku screen with "Power Outage" icon displayed.

During the soak an unusual thing happened... the power went out.  I say that it's unusual because this is only the second time in the 15 years we have been living in this house that I can remember a power outage.  It happened on Sunday while we were all at home and only lasted about 10 minutes.  I found it interesting because it showed off a controversial feature on the Nomiku that I had never tested, if the power goes out the Nomiku will remember the set point and resume once the power is restored.  When this happens an icon lights up on the screen to alert you of the outage.  I say it's controversial because it can be a food safety issue, if the power goes out while no one is around and stays out long enough for the bath temperature to drop in to the danger zone (between 4C and 49C) it could allow harmful bacteria to grow unchecked.  If you don't notice the icon you could end up serving dangerous food.  The way I see it is by resuming after a power outage and letting me know that there was one I get to decide if there is a risk, and take the appropriate actions.  If the same outage had happened while we were all out at work and I was using a circulator that didn't resume afterwards then food that would have been otherwise fine would end up getting spoiled and thrown away.  It would be REALLY nice if the Nomiku folks could add a feature that not only will tell you that there was an outage but also what the bath temperature was when the power was restored, that way you could make an informed decision.  In the meantime I'm looking at buying a digital aquarium thermometer that has min/max capability like this one here.

St. Patrick's Day dinner

Now on to St. Patrick's day.  When I got home from work I pulled the corned beef out of the bag and allowed it to cool in the bag for about 10 minutes.  During that time I quartered some new potatoes and sliced half a head of cabbage in to 1/2" thick slabs.  A corner of the bag was cut off so I could pour off the juices (and there were a lot) through a strainer and in to a sauce pan.  To those juices were added the potatoes and carrots with the cabbage lain on top.  The lid was put on and the flame set to low, after about 15 minutes everything was cooked and we were ready to eat our St. Patrick's day meal with some soda bread and Guinness.  The corned beef was excellent, tender but not falling apart with strong flavors and not too salty (thanks to the rinse).  I don't have a picture, but for dessert I made an Irish Cream bread pudding served with some Guinness caramel.  I'll post those recipes in a future entry.  With the leftover half of cabbage I'm making some home fermented sauerkraut, we'll see how that goes in a week or so.
