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.
AND THAT'S WHAT MAKES A KRABBY PATTY! :)
