What do you think the real secret krabby patty ingredient is?

I think it's just good quality.
Buns, Patty, Pickles, Tomato Sauce, Mustard, Lettuce, Tomato, Cheese
And Mr. Krabbs is just teasing Plankton about a secret formula to the Krabby Patty.

Because I remember an episode that Mr.Krabbs wants to make sure his customers are eating grilled cooked Krabby Patties not machine processed Krabby Patties

it is koral XD

Vinegar & Mustard.

yes mustard,chesse

Hm....well maybe it's something so complex that no one would think of it! LOL. Um.... well, maybe it's money.... It could explain the high prices for Krabby Patties.... Or.... uh.... I got nothing else!

The Krabby Patty secret formula is for the patty only. It contains a rare sauce found in canyons named for King Neptune.

Uh A Krabby Patty :D? Lol couldnt think of anything T-T

i'd say it's love.
