How do I stop my sous vide steak drying out? I have tried various temperatures and times from 55°C to 60°C and from 40 minutes to 4 hours. The colour and texture changes but the meat is always too dry to enjoy.
My mother eats steak well done conventionally and it is much more moist than this sous vide medium rare. The meat is still very red, so it's not over cooked.
I am using sirloin, about 20mm thick. It's 28 day aged, according to the packet. When cooked in a pan it is very nice, as it should be at £22/kg. I have tried presearing plus postsearing and postsearing only. Sealed in Sous Vide Supreme vacuum pouches. They then go into a 30l water bath heated by a Vac-Star Sous Vide Chef 2. The temperature is totally accurate according to my certified thermapen and does not vary at all.
I also tried cooking chicken breast with garlic butter potatoes and carrots, as per Douglas Baldwin's book. Carrots were delicious. Potatoes were hard and bland. Chicken was downright weird. Very unpleasant texture and very dry. I invited a couple of friends who are keen to try sous vide over during the whole process. All 4 of us agreed. The machine is going back.

The machine
My immediate first thought was that you had a bad machine. The Vac-Star Sous Vide Chef has excellent reviews on Vac-Star's website and it looks like you are using it within proper specifications. That would be my first hunch, as nothing else seems particularly out of place. If you are able to come back, since this was over a year ago, it would be curious to see if a different machine solved your problems.
On a side note, I looked up reviews for Sous Vide Supreme vacuum pouches and they seem good, too.
Other things
I looked up for reviews of the I noticed the Beyond Salmon blogger had posted a follow-up experiment with sous-vide steaks that I found had useful data. This summarized it well:
I have noticed this from your post:
Per her experiment, steak A, B and C turned out the best. They also had the lowest temperatures and cooking times:
Steak A: 121°F (49.5°C) water bath for 50 minutes
Steak B: 126°F (52.2°C) water bath for 50 minutes
Steak C: 131°F (55°C) water bath for 100 minutes
It likely would be a good idea to try lower temperatures, and stick to the lower-end of the time scale. Also from the article:
