According to kashrut (the set of laws that govern whether or not food is kosher) and more specifically shechita (the laws governing slaughter), certain types of fat found in cows, Goats and Sheep and known as chelev are reserved for use during a ritual known as korban when they are burnt on the mizbe'ah (altar). Other fats are known as shuman and are kosher. The gid hanasheh, sciatic nerve, is located in the rear of the animal and is also treif (not kosher).
Removal of chelev and gid hanasheh, a process known as porging, is an extremely tedious and complex task which takes a long time to do right and so is thought to be labour intensive and economically unviable. As chelev exists in far smaller - and easier to remove - amounts in the front of the animal, it is often only this part that is eaten unless the animal has been prepared by a very highly-skilled shochet (slaughterer who is highly trained in kosher slaughter) who is able to remove these parts. If not, the hind end is usually sold on to non-Jewish butchers, manufacturers of non-kosher foods and petfood manufacturers.
Only the front half of the cow is used for kosher consumption so technically, any part of the front half.
No, there is no difference in tenderness between kosher and non-kosher beef. The animals are raised in the exact same way with the only difference being the way in which they are slaughtered and that as part of the kashering process, kosher beef is salted to draw out excess blood.
Only if it's kosher.
You'll have to check the label. If there's no kosher-symbol, they are not, despite being all-beef. An internet search provided no information, which suggests that they aren't kosher, but you can only be sure by checking the label. See also:More about kosher foods
Not all cuts of beef are allowed, however, there are kosher steak cuts which come from the front half of the cow such as a rib steak.
NO. Kosher beef has to be killed a certain way and blessed by a rabbi. It is significantly more expensive than normal beef
This is impossible to answer, but the salt content in all kosher meat is significant.
Hindus do not eat beef no matter if it is Kosher or non-kosher.
Beef jerky is made from a part of the cow that i am unfamiliar with but definitely not pork
The is no prohibition against eating spicy beef. The only requirement for religious Jews would be that the meat must be kosher.
Your best bet would be to call a kosher butcher in the Chicago area to find out who deals with kosher organic corned beef if there's such a thing available.
No _____ Because the kashering process draws out so much blood, there is the possibility that kosher beef has less iron than non-kashered beef. However, if you cook the non-kosher meat to death (well done), that would be pretty much negated.
