EGGPLANT
THE BIGGEST CHALLENGE THAT CONFRONTS the cook when preparing eggplant is excess moisture. While the grill will evaporate this liquid and allow the eggplant to brown nicely, this won't happen under the broiler or in a hot pan. The eggplant will steam in its own juices. The result is an insipid flavor and mushy texture.
Salting is the classic technique for drawing some moisture out of the eggplant before cooking. We experimented with both regular table salt and kosher salt and prefer kosher salt because the crystals are large enough to wipe away after the salt has done its job. Finer table salt crystals dissolve into the eggplant flesh and must be flushed out with water. The eggplant must then be thoroughly dried, which adds more prep time, especially if the eggplant has been diced for sautéing. (We prefer to dice eggplant that will be sautéed to increase the surface area that can brown and absorb flavorings.)
Eggplant destined for the broiler should be sliced very thin (about 1/4 inch thick) so that the salt can work quickly. The salt will take more time to penetrate thicker slices and will in the end be less effective. However, when grilling, you want thicker slices that won't fall apart on the cooking grate. We found that 3/4-inch rounds are perfect for grilling.
