Wash and clean the squid, separating the outer sacs from the heads and tentacles, removing and discarding the translucent cartilage, and small sand bag and ink. Rub salt on the outer sacs and rinse them inside and out with cold water. Heads and tentacles should be rinsed thoroughly and cooked along with the sacs after you stuff the latter. Drain and set aside. Heat quarter cup of the oil in a heavy frying pan, then add the onion and cook, without browning, until transparent. Stir in the rice and saute a few minutes, until golden. Blend in the parsley, mint, 2 tablespoons wine, pine nuts, and raisins, and season with salt and pepper to taste. Add enough water to half cover and cook for a few minutes, then stuff the squid sacs with the mixture using a very small spoon and allowing enough liquid in each for the rice to cook. Seal opening with skewers or toothpicks. Place the stuffed sacs with the heads and tentacles in a baking-serving dish. Sprinkle with salt and pepper and set aside. Meanwhile, combine the tomatoes, one third cup wine, and a little salt and pepper in a small saucepan and simmer for 5 minutes. Pour the sauce over the squid and dribble the remaining 2 tablespoons olive oil over the top. Bake in a medium-slow oven (300 F) for 1.5 hours or until the squid and rice are tender and the sauce has thickened. Serve warm or cold.
