Sous-Vide Steak and Salt Experiment

So why bother with another experiment? Why not? This is; at least to me a lot of fun. This experiment has two purposes. It can verify what we already know and possibly debunk traditionally held beliefs.

My first experiment involved Sous-Vide VS Reverse Sear with some additional stuff on Salt and moisture loss. Comparing the results from the above experiment and this one could pose interesting.




I belong to several Facebook groups that discuss Sous-Vide cooking and on occasion the conversation turns to experimentation with salt. The argument goes like this...Should we SV with no salt?, Should we salt right before we SV, is there a benefit to dry-brining or not? Although the first experiment covered some of these issues it was necessary to do another one. As always I thought it would be fun to run another experiment but focus primarily on salt, flavor and moisture loss. Of course flavor is subjective but hard data will provide some insight. What role does salt play when it comes to meat? We're about to find out.

Before you read further you need to understand how I conducted my experiment and what were some of my ideas and protocols.


  • All Prime steaks came from Costco and were similar in size. All about 11/2 inches.
  • I used Diamond Kosher Salt.
  • I used exactly and I mean exactly 1% of salt by weight. I.E if the steak weighed 400 grams I used 4 grams of salt. I have a very precise gram scale so this was easy. 
  • I coated the steaks evenly. Every square inch was covered with the measured salt.
  • Each steak was coated with salt at a precise time. 
  • I made 8 steaks {first experiment) and all had different dry brine times (or not) Steak number #1- Received Salt 40 hrs prior to SV, #2- 24 hrs, #3- 12 #4- 6 hrs #5- 2 hrs, #6- 1 hrs, #7- salted and placed in Vacuum bag and #8- was naked, no salt.
  • Note- #8- received salt at 1% and pepper before sear.
  • Second experiment- Steak #1 Received Salt 40 hrs prior to SV, #2 Salted and placed in Vacuum bag and #3- was naked, no salt. 
  • Note- #3- received salt at 1% and pepper before sear.
  • No plastic wrap was used during the dry-brining. All naked on a try. Plastic wrap does not aid in the dry-brining and it may pull off some of the salt and rub. 
  • All steaks were cooked at the same time.
  • All steaks were SV at 128 degrees right right after they were vacuum sealed. 
  • The first 8 steaks were in SV for 75 minutes and in the second experiment for 150 min. 
  • All steaks received a Cold shock.
  • All steaks were padded with paper towel prior to being weighed after SV.
  • All steaks received a little pepper before hitting the grill. 
  • All steaks were grilled at the same time. None of the steaks received a robust sear.
  • All steaks were allowed to rest 2 minutes before being weighed after sear.

Results will be at the bottom following the gratuitous pictures. 











Ahh the results. First let me say this whole experiment and results are somewhat abstract because it's not just about percentages but taste and texture. If you were to look at the chart #6 had the least amount of moisture loss but was not my favorite. I did not like #8 at all. #2 was OK, #1-4 were the best tasting to me. #1 was my favorite because the salt managed to get into the center of the meat. The salt and the obvious moisture evaporation caused the meat to have a slightly more concentrated flavor (Beefylicious).

Some interesting observations. Having done this many times now this is what I have learned. There are many variables to these experiments and if you change just one of them you will get different results. Fat content, size and thickness of steak, how long you sear the steak and at what temp..etc will yield a different outcome so take this experiment with a grain of salt...pun intended. 

I want you to consider these numbers for a moment. Steak #8- which was SV naked at 128 degrees for 75 minutes lost 8.97% moisture and in the second experiment Steak #3 lost 10.53%. Why??? Steak #3 in experiment #2 was SV for 150 min instead of the 75 minutes. What can we take away from this little experiment? Dry-brining can reduce moisture loss but only under certain conditions.... time and temp variables need to be considered. As you increase the time in water bath more moisture will be lost. In addition if you increase the temp of the SV more moisture will be drawn out. In my opinion dry brining gives a flavor boost and increases the flavor of beef.  

Moisture retention is not always indicative of a great steak. Sometimes less moisture and greater salt penetration will yield a better steak I.E Steak number one. 

A couple more things about the percentage of salt used. In my opinion if you're going to dry-brine for more than 6 hours you should cut the salt down to about .50-.66%. The salt penetrates so well you need to use less. Of course this is my opinion and you may want to experiment yourself. 

My pronouncement is to Dry-Brine for at least 6 hours. In the end it was about flavor and not moisture that produced the superior steak.

Tri-Tip with Ancho & Coffee





If you like beef you will love my take on Tri-Tip!! 




Although I have a love for beef (normally made from Top Round) I find the amount of fat in the cut deficient. The best of the both worlds in my opinion is the mighty Tri-Tip which has a little more fat than the Top Round Roast Beef. The Tri-Tip has more intra-muscular fat and if you want flavor you need fat. If you are unfamiliar with the Tri-Tip it's a small triangular muscle cut from the bottom sirloin sub-primal section. What makes this Tri-Tip a little different is the rub I use and how thinly I sliced it. Of course I will be cooking this hunk of meat using my Sous-Vide and finishing it off on the Weber Genesis Grill at an extreme temp.  


First things first where do you buy a Tri-Tip? I have never seen it at QFC or Safeway but it's always available at Costco. 

Why is it called a Tri-Tip? I am not sure either. I have searched the net and really could not find a great answer. I can only speculate that it has something to do with the way it is shaped and how the fibers run. If you were to slice this by hand it could be a little tricky. You can tell by the picture the meat fibers run in different directions. The picture I provided shows you where the fibers are and of course you want to cut across the grain. After you cook a Tri-Tip the fibers are not as noticeable so it might make cutting a little tricky. I am using a pro-Slicing machine so there is no issue for me.


This recipe is a snap. These are the ratios I used but it's just a personal thing. Montreal steak seasoning (4), Cinnamon (1), Ancho-Powder (4), favorite coarsely ground coffee (3) and Brown sugar (5).  I purchased my steak seasoning from Costco but you can make your own. Mix it all up and apply liberally to your meat. Note: adding Coffee to the rub adds complexity and bitterness that is just wonderful.


So when I say apply liberally I mean cake it on!! You want to impart a lot of flavor into the meat.



Vacuumed sealed!! The meat will sit for 24-48 hours in the refrigerator that way all the flavors will marry and hopefully penetrate the meat (I prefer 48 hours). This is basically a dry rub marinade. Afterwards I will Sous-Vide the Tri-Tip at 133 degrees for 9 hours. For details about Sous-Vide Tri-Tip Click-HERE.
After the Sous-Vide bath I cooled the meat off in a Ice bath then refrigerated the meat overnight. The next day I fired up my Weber Genesis to about 725 degrees to brown the outside of the meat. Prior to putting the meat on the grill I dried the meat off with paper towels to remove excess moisture to facilitate browning. The meat will not brown very well if moisture is excessive. I also applied little bit canola oil spray to the meat because oil acts as a conduit for heat distribution and helps with the browning. 

After I browned up the meat I cooled it once again in the refrigerator for a couple of hours. Now all you gotta do is slice away and enjoy. 



I would also suggest reserving some of the rub and processing it through a spice mill into a fine powder to sprinkle on the meat after it's sliced up. Now go make a great big sandwich!!!



















Update- 3/27/2015
133 at 8-12 hours produced awesome results. This time I used Certified Angus Beef. Not sure if this made a difference but it was awesome.
