It probably tastes like..... A SANDWICH! But that can't be right. All the characters (except Squidward, he only admitted it in one episode) say that it's so much better than a normal sandwich. It's probably just delicious. I've never tasted professional-made-by-Spongebob ones, I've tasted fake ones though.
I've got it! ten drumrolls, pleass! ( :drumroll: drumroooooooooll)
A Krabby Patty is made out of
1) in the patty: beef, kelp, crab meat, mayo, and bleu cheese
2) the works: seaweed (instead of lettuce), pickle, tom-ah-to, onion.
3) the secret sauce: bbq sause mixed with a few drops of tobasco (for that little 'zing' if ya know what I mean :( ), honey mustard, and kechup (which is why all but the old customers put no condiments on their sandwich).
4) all on two lightly toasted sesame seed buns.
yes, in socal.. its good. :( its also in other places, i think.
