Cut potatoes lengthwise into thick wedges; place in 13"x9" (3L) baking dish. Whisk together water, lemon juice, oil, garlic, salt, oregano and pepper; pour over potatoes, turning to coat evenly. Bake in a 325F oven, gently turning occasionally to keep potatoes well moistened, for about 2 hours or till potatoes are very tender and moist and most of the liquid has evaporated. Serves: 8
