What is the name of the secret formula Plankton constantly tries to steal?

Plankton constantly tries to steal the Krabby Patty secret formula.

The formula is the closely guarded recipe for the Krabby Patty, the signature burger sold at Mr. Krabs’s Krusty Krab. Plankton believes obtaining it would let him reproduce the burger, attract customers to the Chum Bucket, and finally defeat his business rival.

The Krabby Patty first appeared in the series’ pilot episode, “Help Wanted,” which aired in 1999. SpongeBob works as the Krusty Krab’s fry cook and prepares the burgers, while Mr. Krabs protects the formula as a valuable trade secret. The recipe itself has never been fully revealed in the series, which keeps the joke and mystery alive.

The wording can cause a minor mix-up: characters may call it the “Krabby Patty formula,” the “secret formula,” or the “secret recipe.” These refer to the same thing. The alternatives listed here are not established objects that Plankton is famously trying to steal; his recurring target is specifically the Krabby Patty formula.
