Being a Northerner, I've always just winged it, going with seasoned flour rather than corn meal, and vegetable oil rather than bacon grease. But I'm definitely giving this recipe a try.
But not for a few months. Fried green tomatoes are an end-of-the-season treat for me, when the weather turns too cool to ripen them properly and first-frost is on the way. Right now I'm still eagerly counting the days until my first ripe tomato.

A fun variant is to fry up (sauté really) green cherry tomatoes in bacon grease, with or without cornmeal - they have a tartness you don't find in regular tomatoes.
My herbs are busting out of their pots, especially the basil and oregano. Maybe we could get my oregano and basil together with a couple of your tomatoes for one heck of a fresh pasta sauce and/or bruscetta.
I will not say mess, though. Yet I still can't get rind of that insipious all yall.
