Sous-Vide Petite Tenderloin

Posted by johngl

A couple of years ago, while watching Iron Chef America, I noticed this thing called an immersion circulator that is used in a cooking style that is generally referred to as sous vide.  The price of the immersion circulators ($1400+) forced me to rethink this situation.  I am still trying to justify a $5000 stove (yet to be purchased).

Oh, to find a work-around.

When I went back to work on Jan 5, everyone was talking about the Wii Fits that Santa had given them.  When asked what Santa gave me, I said a “Sous vide controller”.

“A what?  What game is sous video?”
“It’s a cooking thing,” said I.
“Oh”

Anyway, the controller arrived and I tried it out last night.

petite tenderloin and cous cous

This is a petite tenderloin with pearl cous cous.  Pretty damn tasty.

Start with a tenderloin:

By now, you should be able to go from a bagged loin to parted out in less than 15 minutes:

tenderloin bits

From the top, that is bits of silver skin and fat (save for stock), the chain (scrape the sinew for burger meat), a couple of petites (I tied these together), and the whole loin.  Dressed and finished, the petites and loin came out like this:

These went into my dry-aging fridge and after three days of aging, the petite looked like this:

I went with the petite because I wanted to give the controller a test drive on a small piece of meat.  I will be doing the large tenderloin later today for another wine salon (Rhone).

To prepare for the sous vide, I hit this with some finely chopped sage and thyme, garlic powder, salt and pepper, all stirred into some melted butter and layered it on pretty thick:

buttered and ready

This then gets stuffed into the FoodSaver bag and evacuated:

bagged and ready

So now we are ready for the water bath portion.  Think of this as a hot tub for food.  We’re looking for a constant temperature for relatively long periods of time.  To do this, we need something to control the temp:

Since I am pretty anal, I wanted to check the unit’s calibration so I rounded up a couple of probe thermometers that I keep around for grilling.  The one on the right is a remote unit that I can carry around while the other part remains stuck in the meat.  It looked like probe central in the roaster full of hot water:

I just drop the bagged meat into the hot water and left it alone for a couple of hours.  It came out looking like this:

a little on the gray side

It lacks some color and that wonderful crust we usually want on our beef.  The solution is to sear it off in cast iron or hit it with a torch.  I wasn’t in the mood for the torch last night, so I opted for cast iron.  It worked nicely.

And a couple of minutes later (after a short rest), the meat looked beautifully cooked:

after a rest, slice it up

Note how the color goes right to the edge.  Yeah, I like that.

We made up some pearl cous cous for a side and plated up:

great dinner!

Paired with a 2005 Lot 35 Cameron Hughes Cabernet Sauvignon from the Yountville District, this was a really great experimental dinner (experiments don’t necessarily turn out quite so well).  I am a happy guy.

The wine was inky colored with a nice purple edge and aged in 100% French oak.  It tastes of dark cherry and currant with a hint of prunes.  There were some chocolate notes as well, so I grabbed some 66% chocolate and gave it a try.  Perfect match.

I will probably be doing several sous vide posts and let you know how the Auber Controller holds up over time.  So far though, it is a great toy that didn’t break the bank.

The best things in life should be shared!

    Your pictures look awesome!
    I am using the same temperature controller device under a different brand (Sousvidemagic) from freshmealssolutions.com and paired with a commercial Tiger rice cooker to make a 14L constant temperature bath.
    The results are just as good as a $1000+ immersion circulator and can do other things like cooking soup and stew in the pot without bags.

Speak up, you know you want to!
