SOUS VIDE
Slow Cooking Is Back… And It’s Better Than Ever!
Some things are just better when they’re done reeeeal slow. Food is one of them. Like many chefs out there, I have embraced the technique known as ‘Sous Vide” more and more. Funny how we think of this as a ‘modern’ way of cooking. The truth is ‘Sous Vide’ is simply a fancy name for ‘under vacuum’. Leave it to the culinary world to make things sound more expensive, right?
Anyway, cooking food at very low temperatures for extended periods of time is really nothing new. (Quick, how many Crock-Pots do you buried in that cabinet?). So what’s the difference you say? Well, Sous Vide uses a bit more science than that 1960’s crock-pot.
First, the food is vacuum sealed in plastic bags and then it is placed in a circulating pot of water. That pot of water’s temperature is controlled by an electronic device called a PID (similar to how your furnace thermostat works). BUT…. this is no ordinary thermostat. The PID’s job is to electronically switch ON and OFF the heat source for the water. A small pump circulates the water which greatly increases the ability to maintain a steady temperature. What’s ‘modern’ about this is that it enables the user to dial in an EXACT temperature of the water.
“Big Deal, That’s Just A Fancy Crock-Pot” you say, right? Here’s the really cool part…. the PID is so precise that it can maintain the water’s temperature to within 1/10th of a degree! So, I guess it’s sort of like Crock Pot cooking if it were done by Bill Ney The Science Guy.
[USELESS FACT #1: Sous Vide uses a device called an Immersion Circulator. Designed for medical science labs long long ago, some hungry laboratory nut-job in the 1960s decided to cook with it (thank you lab geek!). ‘Sous Vide’ is far more marketable a term so it wins. I mean, would YOU order the “Immersion Circulator Short Ribs”?]
So what does all this mean for your steak? Well, imagine the ability to dial in a temperature for your steak and have it cooked to that EXACT temperature! EXAMPLE: I love my steak rare. I can set the water bath temperature to stay at 127.5 degrees. And it will STAY at that temperature……no more, no less. So it is literally IMPOSSIBLE to overcook your steak… even if it sits in that water bath for 2 days! Try leaving your steak on the grill or in the oven for 2 days!
Another benefit is that the slow cooking process slowly breaks down the muscle fibers and fat within the steak. Result?.... a really REALLY juicy steak that is the same degree of doneness all the way through, NOT just in the very middle (check out the Sous Vide Vs Grilled Steak pic attached to see the difference).
“But I like Grill Marks On My Steak!”. No problem so do I!!. A great advantage to having your steak cooked to the exact internal temperature you want is that it can be very quickly seared or grilled over a hot (I mean REALLY hot) heat source to get that crust you crave. A dangerously hot cast iron pan is my choice here (set over high heat for 10 mins……be prepared for smoke!).
While they are still quite expensive ($500 and up), Immersion circulators are quickly becoming more compact and affordable to the home cook.
HOWEVER!!...if there is a will, there is a way……Chef’s are cheap by nature so did I go out and purchase one of these expensive machines?? HELL NO! The internet is full of DIY projects to get this technique in your kitchen today.
WANT TO LEARN HOW ? In my next post, I’ll show you just how to do just that without breaking the bank. STAY TUNED!
