This is a moment to behold. A youtuber made an 11 minute video that culminates in him admitting he was terribly mistaken his whole life? Give this man a medal, some kind of souvineer. That's something special.

A youtuber admitting that he was wrong. Now I truly have seen everything! I love the energy in your videos!

Butter contains 15 or up to 30% water which pretty much means you boiled your steak in a little bit of water. Because of osmosis the flavors and minerals inside of the meat get sucked out into the juices so you're basically making buttery beef broth. That of course means you lose a lot of flavor within the steak.

I’d like to see a 3rd option with no butter in the sous-vide but finished with melter butter after searing.

Wow, not many ppl would admit their mistake this openly and genuinly. thumbs up!

I think you need to add a compound butter after searing. The problem with adding butter to the sous vide bag could be that the meat flavor infuses into the butter, only to be lost when most of the butter is not used. Adding the butter after searing could add richness with no loss of meat flavor.

My theory is that butter acted as a "solvent" carrying away flavour stored in the beef fats.

Coming back to this video after four years Guga and your commentating and energy in your videos has come up so much since these videos back in the day! Absolutely love the progression of this channel

I suspect it’s because you used butter before the sear. Burnt butter is not tasty. I usually sear in a pan, and only add butter to the pan in the last 30 seconds. I’d love to see a comparison where you melt a little butter on the steak after the sear... 👍

Guga: “We are not scientists.”

I can’t say how much I appreciate your authentic reactions to this experiment, Your truthfulness shines through, even though you had preconceived opinions. Thanks for that, it only increases the trust we have in you.

can we just appreciate how much Guga's narrating voice has improved since these older videos? he sounds so bored in some of these older ones lol.

I do not leave positive compliments often. But you deserve it. I love how you admit your wrong so amicably and all you care about are results. You are awesome and please watch where you step cause the pedastal i put you on is extremely high. You rock. Your talent, personality, and taste are fun and informative. Thank you so much.

I stopped cooking in the bag with butter and things got better. Then I didn't season at all while bagged, instead only salting after sous vide but before searing and wowwee I noticed yet another improvement. Before, meat started to take on a ham-like texture (when salted prior to bagging), but when I started salting right before searing the true texture of the beef stood out. I always sear in a screaming, smoking hot cast iron skillet with a neutral oil and browned butter; 30 to 1 minute per side constantly moving creates a crust that's out of this world. Season again after searing and add pepper at this point. All of these processes are sooo counter intuitive to what I learned with more traditional methods but really do produce something I like a lot better.

“All this time I was wrong” 😯😯😯 he is the wisest youtuber I have seen in a while. Respect.

"we are not scientists" conducts single blinded control trial to test a hypothesis with a clear outcome from multiple independent assessors

Here's an explanation: The fat/oil/lipid molecules in the butter dissolved a lot of the fat-soluble (non-polar) flavor compounds in the meat. So what happened here was: a lot of the meat flavors were left in the plastic bag.

A suggestion: try browning the meat with butter after the steak has been removed from the sous vide bath.

GUGA!! I’ve been watching you for almost 2 years now? What ever, I just had to stop to tell you how much comfort your videos bring me ever since my dad passed. You look so much similar to my father and your smile, I picture his face. Your humor, smile etc. you bring me so much joy guga. I came across this old video and it’s sweet to see how far you’ve come and I pray you go even further than you’ve already come 🤍 I hope and pray you reach further than the moon and stars ✨

Just got a sous vide for Christmas and have been watching so many of your videos. Very entertaining, it's so refreshing to see foodies that aren't pretentious. Love the enthusiasm! We love the blow torch music too!
