Even if you want the pot to become forbidden, nevertheless the liver may not be cooked in it.
 When half-roasted, it is considered to be edible.
 This is only post facto, after having been roasted after being pierced by a knife. Initially one may not simply pierce holes in it, if it is to be cooked after having been roasted, rather it must be opened at its length and width.
 Meaning that one cut the sinews and the vessels to the side of the gall removing some of the meat of the liver along with it. This is permitted in the first instance even if it's to be cooked.
 The reason is because of the salt that is attached to it. There is also a fear of maris ayin, that the food will become red. Also meat that was roasted on a stick and is now to be cooked should be washed off first.
 Meaning that even if it was cooked without being salted it is permitted. The reason is because it is so busy expelling blood that it won’t absorb any. If it was cooked with other meat, that meat is forbidden along with the pot.
 Even if not salted. The rule of “as it absorbs, so will it release” apply even without it having been salted.
 The reason is because there is an opinion in the Gemara that if it was extensively cooked, it is forbidden.
 Even if it was salted as required, washed before being cooked, had been cut along it’s length and width, and even placed face down during salting, it remains forbidden. If it happened that a Rov ruled it permissible, we do not contradict his words and we will permit everything, including that which was cooked with it.
