To answer the first question:
Okey. First, you hunt yourself a shark. Do NOT eat it immediately, you'll die. You have to wait couple of months or so.
You cut it down in pieces, the ones my grandpa used to make were shaped like bread. Blessed be his memory.
So. You cut it. You put it in vacuum packings, then bury it. For months. Then you take it up, most people cut it in little squares and eat with toothpics. I used to eat it in bigger slices, like bread. Now I settle for the dices.
Beware, the smell is horrible. The taste is even worse. But you're not a real man (
) unless you eat shark
So, GO ON ALL AND GET YOURSELF A SHARK AND FOLLOW THIS BEGINNER'S GUIDE TO SHARK-EATING!!!!
