“ The meat need not be thoroughly roasted. A simple roasting will suffice and will have brought out any blood that would have come out.
[3] The Tur writes that any blood that drips onto the grill is problematic, for it is considered as surface blood (b’eyn) and is not subject to the rule of “as it absorbed so will it release.”
[4] The reason is because we rule that the lower item is the dominating item (tatai gavar) , and the blood is as a hot food.
[5] This is according to the Mechaber, however we hold that all problems involving roasting and salting requires sixty. ”

“ If they are stuffed they are subject to the same rules as have being cooked, and require salting just as any other meat to be cooked. It is customary to act stringently when roasting meat that has not been salted [12] and to refrain from always flipping over the skewer so that the blood will flow, but post facto, one need not worry. In makes no difference in all this if one wishes to eat after roasting, or if one wishes to cook it afterwards. ”

“ Regarding that which the Rema says “or that it was salted without being first washed, and then roasted, is still permitted” is even in the first instance. It is phrased in a post facto fashion to tell us that it must be washed after being salted, before being roasted. ”

“ Our case would not require us to place any salt in the vessel at all for when the Gemara ruled that salt must be placed in a vessel it was referring to meat that was not yet roasted. The reason the Mechaber did not mention placing salt in the vessel is because he is speaking of meat that has already been properly roasted. This ruling is accordance with all authorities.
סעיף א הצלי אין צריך מליחה לפי שהאש שואב הדם שבו מעצמו. אבל אם דם אחר נטף על הצלי, אפילו אותו דם הוא צונן -- לא אמרינן שהאש שואבו, ואוסר ממנו כדי נטילה. ”
