Wash the squids very well. Remove the long thin membrane in the head and slit the eyes to bring out the ink. Place the squids in a saucepan with vinegar, 6 cloves garlic crushed, salt and pepper. Cover and cook slowly until the squids are tender. Cut cooked squids into 1/2 inch slices crosswise. Crush remaining garlic and saute in a little lard in another pan. Add the onion and tomatoes and cook until tomatoes are very soft. Add the squids and the liquid in which they were boiled. Simmer for 7 minutes. Season with salt, pepper and vet-sin.
