Barbecued Ribs and Grilled Corn

Rinse the ribs, pat dry and separate. Place in boiling water and simmer for about 20 minutes over low heat. Drain and pat dry. Peel the garlic and onion, and chop coarsely. Rinse the chiles, cut in half, remove seeds and finely chop. Add the chiles to a pot with the onion, garlic, sugar, salt, pepper, tomato paste, vinegar and Tabasco, and boil with 200 ml (approximately 7 ounces) of water. Allow to simmer for about 10 minutes, then remove from heat and let cool.
