Sliced in smallish rounds, lightly breaded, served on a sour cream sauce sprinkled with diced chives, these fried green tomatoes offer exactly the right combination of garden freshness with batter-fried flavor. Somehow, in spite of all that preparation, these succulent mouthfuls manage to stay firm at the core. They are a perfect expression of the South--juicy but fried--with a sophisticated Bishop Arts flair.
