I’ve never tried it, but I think you’re talking about Jiffy Mix? Makes Great Corn Bread Muffins. A bit sweet, but good.
Typically, a flour crust is flaky with large chunks of crust like traditional fried chicken. Corn meal crusts are grainy and more suited to seafood like fish (catfish in particular) and crab claws.
A box mix like jiffy mix is a mixture of flour and cornmeal which a lot of people use on seafood. It also has some fat added to it which would help in the oven baking process for “oven frying”.
But, in the end, due to the corn meal, it’s going to be a granular crust, like saw dust, so don’t expect the Colonel’s Crust if you try this.
Not saying it won’t be good. But a granular crust will be “different” for chicken, but somewhat expected for fish or oysters. Should be fun though, kind of like the bread crumb based “Shake-N-Bake” items but with more sweetness.
A spritz of Soy or Lemon might add a nice cutting bit of acidity/salt to that sweetness that could put this over the top.
Just a thought.
