2 cups plain yogurt
1 eggplant, about 2 pounds
3 tablespoons olive oil
3 tablespoons minced fresh dill
2 cups chopped scallion
1 teaspoon minced garlic
1½ tablespoons fresh lemon juice
salt to taste
tomato wedges and imported black Greek olives for garnish
Preheat oven to 350 degrees.
Line a mixing bowl with cheesecloth and empty yogurt into it. Bring the edges of the cheesecloth up to make a bag; tie with string and suspend over the bowl to let yogurt drip. Let stand in a cool place for 2 to 3 hours. The yogurt will become as thick as sour cream.
Meanwhile, prick eggplant, place on a square of aluminum foil in a baking pan, and bake for 1 hour, or until very soft. Split in half lengthwise and cool. Remove as many seeds as possible, and scrape pulp well from skins. Place pulp in a colander and let drain.
Put eggplant pulp in a bowl and add yogurt. Mix well. Add remaining ingredients and chill thoroughly. Garnish, if desired, with tomato wedges and olives.
