My first, gut reaction was something along the lines of:
"Hmm. No, wait. Ew. Ew. Ew. Ew. Ew. Ew. Ew. Ew."
Which, translated, is essentially one split-second of palate-confounding juxtaposition, coupled with about a minute of gagging in the wake of a cold, slimy, aftertaste.
I will say this about dipping your chicken tender in soda: It's not good. The texture is appalling. The cold soda turns the tender to an unappetizing cold, soggy stick of poultry disappointment. It's the (even more) hedonistic, chicken finger analogue to Kobayashi dipping his hot dog buns in water and swallowing them like a duck.
I really did have an open mind here... I wanted to like it. And at first, the sweet coating of the soda atop the tender actually wasn't horrible; it reminded me of Dr. Pepper-infused BBQ sauce. But the texture of the soaked tender was like breaded ipecac.
So as I sit here, with a ruined chicken tender (and a ruined soda, too!), I have to think to myself, that perhaps not all beloved food traditions have redeeming qualities. Not every culinary quirk needs objective justification. People do weird shit to their food. Weird, baffling, health-averse things.
And honestly, sometimes it may be better to stay out of it.
Especially when chicken tenders are involved.
