In The Stalking Zuko Series, Katara says this word for word in her narration when Sokka plans to introduce a sixth flavor into five flavor soup... fireflakes. For context, Katara has, so far, gone from absolutely loathing fire flakes to slight acceptance of them, not unlike her relationship with Zuko.
You can't do that to five flavor soup.
You just can't.
