Hi Ben and welcome to the forum

You've beat me to it - by that I mean I bought a Sous Vide Magic controller and a cheap rice cooker to use as the water bath about a month ago. I was hoping to adopt the technique for lamb or chicken in BIR food.
I've read so many times that raw fresh garlic can overpower the food after a long cook in the plastic bag but it sounds like you didn't have that problem?
So far I've done:
Pork belly for 24 hours, very nice. Can't rememer the temp I used.
Pork Chops at 62 degrees - a little dry and rubbery.
Rump steak at 60, was a little dry so next time I'll try 55.
Lamb neck fillet, 70 degrees for 48 hours. Wow that was tender!
Chicken breast at 62 degrees. This turns out great but a few red spots here and there.
I hope to post some of my experiments over the next few months with pre-cooked chicken and lamb in a BIR context.
Cheers,
Paul
