Just slice it into rings and eat it, leaving the outer skin on the plate. Pineapple is delicious and you don't need to caramelise it or pour vodka over it. Get it down your neck! Why can't people just enjoy the good things of life, like fruit, just as they come?
Yes pineapple contains an enzyme that breaks down meat tissues. That is why it is traditionally served on gammon. It is a left-over combination from the days when meat was really tough. Popping a slice of pineapple on a piece of gammon is not going to make the gammon noticeably more tender though, and anyway who needs to make gammon tender?
