Here's what I think the "secret" Krabby Patty formula is,
mix up some ketam meat, kelp and seaweed then form it in a patty shape then put the patty on the grill cook until it's well done then put in a bun with, cheese, lettuce, tomato, sos tomato slices, pickles, and onions.
There have been so many different ideas thrown out..but I don't think they've revealed the actual secret ingredient of the Krabby Patty secret formula.
