Kung Fu Panda (2008)
Disappointed in himself, Po returned from The Jade Palace for not being able to understand the blank scroll of the Dragon Warrier. Mr. Ping finally told Po the secret ingredient of the secret ingredient soup.
Mr. Ping: The secret ingredient is… nothing!
Mr. Ping: You heard me. Nothing! There is no secret ingredient.
Po: Wait, wait… it’s just plain old noodle soup? You don’t add some kind of special sauce or something?
Mr. Ping: Don’t have to. To make something special you just have to believe it’s special.
[Po looks at the scroll again, and sees his reflection in it]
Po: There is no secret ingredient…
Then, in the end, when Tai Lung got hands on the scroll by force and saw nothing, Po then had already understood the meaning…
Tai Lung: Finally… oh, yes… at last, the power of the Dragon Scroll is *mine*…
[He opens the scroll – and stares at it]
Tai Lung: It’s nothing!
Po: It’s okay. I didn’t get it the first time either.
Tai Lung: What?
Po: There *is* no secret ingredient. It’s just you.
