(9) If the skewer is removed from the fire while there is still a flow from the meat, the meat is still permitted, but the skewer become forbidden. It seems that it is not forbidden to remove it from the fire even if not fully roasted.

The meat and skewers should be permitted because of the rule “as it absorbed, so will it release.”
