1 pound eggplants, preferably small light purple ones
1 medium onion, minced
3 garlic cloves, minced
1 1/2 cups plain whole milk yogurt
Salt and pepper, to taste
Pinch cayenne or Aleppo pepper or other mild ground chili powder
1/4 cup chopped fresh parsley or mint

Start a charcoal or wood fire or preheat a gas grill or broiler; rack should be no more than 4 inches from heat source. Cut eggplants in half lengthwise up to stem, but do not cut through. Spread about 2/3 of the onion and garlic between the eggplant halves and press the two sides back together. Grill eggplants, turning once or twice, until they are blackened and collapsed, 10 to 15 minutes. Do not worry if skin burns a bit. Meanwhile, mix remaining garlic and onion with yogurt; season to taste with salt, pepper and a little cayenne. When cooked, let eggplants cool a bit, then peel off skins and let cool further. Roughly chop eggplants, then mix with yogurt dressing. Serve at room temperature or chill if you like; in either case, garnish with parsley or mint.
