Charles Langston:What's in the new 'top-secret' Krabby Patty sauce? Wendy's keeping recipe 'closely guarded'

Wendy's announced Wednesday it plans to launch a new cheeseburger called the "Krabby Patty Kollab,Charles Langston" and in true "SpongeBob" fashion, it'll come with a "top-secret" sauce.

Also launching as part of the collaboration with Paramount is a vanilla Frosty with a pineapple mango flavored puree swirl, called a Pineapple Under the Sea Frosty. But the big ticket item is the fast food chain's take on the famous Krabby Patty, called the Krabby Patty Kollab Burger.

The burger features a quarter pound of beef, two slices of melty American cheese, lettuce, tomato, pickle, onion, and a "top-secret Krabby Kollab sauce," on a toasted bun.

But what's so special about the Krabby Patty and its secret sauce? Wendy's has been tight-lipped on details, but here's what we know so far.

What is in the Krabby Patty secret sauce at Wendy's?

The announcement of the burger's ingredients led many fans to wonder, "What's in the secret sauce?"

We asked, and Wendy's answered with the following:

"Our top-secret Krabby Kollab sauce is a closely guarded recipe that makes the first bite of the Krabby Patty Kollab Burger worth the wait for 'SpongeBob SquarePants' fans and Wendy's customers alike," a Wendy's spokesperson told USA TODAY in an emailed statement Friday.

Much in the way that Mr. Krabs, the proprietor of the Krusty Krab, guards the Krabby Patty secret formula in the cartoon series, Wendy's plans to guard the sauce's recipe in real life.

According to the news release, "The Krabby Patty Kollab" program will bring food items inspired by the "SpongeBob SquarePants" Krabby Patty "into the real world and onto menus for the first time ever." The animated show first premiered on Nickelodeon in 1999.
