“ We follow the Rashba who rules that the hair is not considered a problem for the purposes of salting. The cutting stated here is for those who want to be more meticulous, however the halacha does not require it for the head is as any other thick piece of meat. Regarding the brain, it suffices to make a hole in the bottom of the skull to allow the blood to flow out. ”

“ The Rashba writes that only regarding blood, do we say that salting has no effect on vessels to bring it up, however in the case of the fish it would be forbidden. The Rashal holds that even for biblically prohibited items, salt has no effect to bring out the taste.
(8) It seems that they should be forbidden as the Mechaber holds that regarding fish we do not say that while they release their blood, they will release other blood for four reasons: a) Fish are a permitted entity and once absorbed with blood, become forbidden.

“ Only if cut with a knife will you have to go back and re-wash, because through the pressure of a knife, blood is brought up to the surface. However, according to the Ran who holds the reason for the washing is to soften the meat, it would make no difference how many cuts are made, and re-washing would not be required. However, halacha follows the opinion that the rinsing is due to blood, therefore re-washing will be required even post facto. ”
