There is nothing wrong with using a hair dryer (on Cool) to remove moisture from food, like a chicken. Probably should use a dedicated hair dryer, but regardless, it is a great technique.

It is completely valid. Hell, Anthony Bourdain was an early advocate. The major takeaway from that recipe though is the incremental method of cooking the chicken. I’ve done it twice, sans hair dryer as I was able to allow the chicken to sit in the fridge long enough the first time and the second time I realized I had no idea where my wife keeps her hair dryer. That incremental method of cooking the chicken yields amazing results. Truly worth doing. Maybe not every time, but definitely from time to time.
And use a hair dryer! Don’t be afraid!
edit: As this pertains to Sous Vide cooked meat, I wouldn’t worry about moisture past blotting it with paper towels. The way you sear it is more important. I agree with that assessment. Throwing it in the freezer for 5-10 minutes before searing will protect against overcooking during the sear too. Apologize if my hair dryer rant was a bit off topic given this thread is specifically aimed at sous vide cooking. Just can’t help myself when hair dryers are brought up I guess!
