Suzanne F: I've used this method for years when making certain cold, Chinese chicken dishes. Since the surface of the meat being cooked is exposed to water in excess of 161°F for greater than 15 seconds, the bacteria present is dealt with. As long as the meat is protected from a new contamination, there shouldn't be any problem. Fat Guy: this is an efective way of reheating pre-cooked sausages, such as bockwurst, boudin blanc, etc., without heating the center past 160°F and without the sausage bursting. I place the sausages in water, bring to a near boil, and immediately remove the saucepan from the heat, After sitting for 10 minutes, the sausages are heated through without becoming dry.
