Until then, I found a recipe:
https://www.simplyrecipes.com/recipes/fried_green_tomatoes/If you can find it, use fine white cornmeal, which is the primary cornmeal used in the South. Buttermilk adds flavor and tang, but is not strictly necessary.
Ingredients
3 medium, firm green tomatoes
Salt
1 cup all-purpose flour
1 Tbsp Cajun seasoning (optional)
1/2 cup milk or buttermilk
1 egg
1/3 cup cornmeal
1/2 cup fine dry bread crumbs
1/4 cup peanut oil or extra virgin olive oil
Method
1 Slice and salt green tomatoes: Cut unpeeled tomatoes into 1/2 inch slices. Sprinkle slices with salt. Let tomato slices stand for 5 minutes.
2 Set out shallow bowls with coating ingredients: While the salted green tomato slices are resting, place in separate shallow bowls: the flour and Cajun seasoning (if using), buttermilk and egg, and breadcrumbs and cornmeal.
3 Dip green tomato slices in flour, egg, then breadcrumbs: Heat the peanut oil in a skillet on medium heat. Beat the egg and the buttermilk together. Dip the green tomato slices in the flour-seasoning mix, then the buttermilk-egg mixture, then the cornmeal-breadcrumb mix.
4 Fry the green tomatoes: In the skillet, fry half of the coated tomato slices at a time, for 3-5 minutes on each side or until brown.
Set the cooked tomatoes on paper towels to drain. These fried green tomatoes are fantastic with a little Tabasco sauce or remoulade.
