I have a hard time finding hints on how to sous-vide guineafowl breasts properly. Traditionally in an 140-165°C oven they’re really hard to get right. Some of the few recipes i’ve found place them in a bath of ~65-70°C for some 30-120minutes. This feels a bit short for my taste, as i’m not sure whether the breastmeat will reach the desired temperature at its core in such a short time. So the time-temperature for this cut in sousvide would be one point i’m interested in.
Furthermore, i’ve often heard that poultry especially contracts muscle fibers when “temperature shocked”. So i guess i’d start the bath with cold water and cold meat, to get a slow heat-up.
The last question is for sauces which could go well with it. The meat itself should be way more aromatic than many other poultry meats. Due to this i’m not sure if using the liquid from the sous-vide-bag as a base for sauces (i.e. fruity riesling butter sauce with caramelized onions and some mushroom bits? Maybe others?) is a good idea. On the other hand, if not using the meat-juices there’s pretty little base you can make a sauce of … right?
