To roast the eggplant: Cut the eggplant in half, lengthwise and salt it. Let stand for 30 minutes. (This will remove some of the moisture). Preheat oven to 425. Wipe off water and salt, then place eggplant flesh side down onto an oiled sheet pan. Roast for 40 minutes or until very tender. Let cool and scoop out eggplant flesh.
