Toasted wheat germ and cornmeal combine to create a light, crunchy crust for this delicate white fish, which also tastes wonderful with homemade tartar sauce. Soaking the fillets in milk before cooking plumps the meat and helps keep it moist.
Place fish in a large dish and cover with milk. Refrigerate 30 minutes.
In a large skillet over medium heat, cook scallions in 2 tablespoons oil until softened, about 1 minute. Stir in garlic and corn; cook 3 minutes. Reduce heat to very low, cover, and keep warm.
Combine wheat germ, cornmeal, salt, and cayenne in a large, flat dish. Whisk to mix. Remove fish from refrigerator and drain off milk. Dredge each fillet in wheat germ-cornmeal mixture and place on a baking sheet. Heat 2 tablespoons oil in a large, nonstick skillet over high setting. Place half the fillets in pan and cook 3 minutes on each side, adding more oil and adjusting heat slightly if they start to brown too quickly. Transfer cooked fillets to a platter. Add remaining 2 tablespoons oil to skillet and cook remaining flounder.
Just before serving, stir basil and chives into corn ragout. Season with salt to taste. Spoon some ragout onto individual plates and top each serving with a fish fillet and lemon wedge. Let guests squeeze lemon over fish at the table.
