Peel and salt for a big improvement in texture and flavor
Peel the eggplant in stripes (unless you're using a tender-skinned variety) and then slice or cube it, depending on the recipe.
Because globe eggplant and other large varieties usually have tough skins, peeling it is a good idea, especially if you're serving it in chunks or slices, as with the Eggplant with Tomato & Garlic Sauce and the Grilled Eggplant Sandwich. Even then, I don't like to remove the skin entirely. Instead, I partially peel it in a striped fashion, the way Turkish cooks do. For the Eggplant with Fragrant Spices and the Eggplant & Pepper Dip, you'll be char-roasting the eggplant and separating the flesh from the peel, so keep the skin on during cooking to keep the eggplant intact.
Globe eggplant works deliciously in just about any eggplant dish, provided you salt it first. Salting, also known as purging, accomplishes two goals:
Preventing greasiness. Globe eggplant, whose flesh is especially spongelike, tends to soak up more oil than other varieties. If you've ever brushed a raw, unsalted slice with oil, you've probably noticed how readily the eggplant absorbed it. According to food scientist Harold McGee, salting draws out water and helps collapse the air pockets in globe eggplant's spongy flesh. This makes the eggplant much less able to soak up lots of oil during frying or grilling.
Reducing bitterness. Salt pulls out juices that carry bitter flavors sometimes found in globe eggplant. (Agricultural scientists say that the bitterness, as well as the mouth-tingle that some people get from eggplant, is caused by alkaloids, bitter-tasting compounds concentrated in and around eggplant's seeds.) Salting may also serve to overpower any bitter flavors.
