A note about gelatin...
One of my guilty pleasures our sour gummy bears/worms. Interestingly enough, one day I was eating some and offered some to a Muslim co-worker. He said, "No thanks, because I can't eat gelatin because it may come from pig bones."
Ever since that, if I were to eat any gummy anything with gelatin on it, that is is also kosher. That is, if it isn't good enough for a stinky Muslim to eat it, then a Jew shouldn't definitely not eat it.
