Chicken is unfortunately one of the less effective things to cook this way. At the times/temps I'm comfortable with, breasts get mushy. Legs, on the other hand, "pink out"; the proteins from inside the bones leach into the flesh and give a bloody appearance which I can't get past.
But really, sous-vide, medium rare chicken breast has a taste and texture you'd never think chicken breast could have. Same with pork, it's a revelation on all the things you miss out in the world due to prejudice and bad information.
EDIT: I've never gotten mushy breasts tptacek, how long are you cooking those things for? I do 1.5 hours@57-60C or so.
a good thoroughly cooked, yet juicy and delicious roast chicken is still one of the most basic, yet difficult, dishes to prepare.
That certainly has an effect on my thinking, it's not that I don't like a more rare presented chicken, it's that we're conditioned to think of it causing illness because of the laws around it's distribution.
