Poach chicken pieces until almost tender, about 15 minutes, in 1 litre well-seasoned water. (I add chicken base, basil, oregano and rice wine) Add bay leaf, 2 cloves of garlic, peppercorns and salt. Let chicken cool in broth. Saute onion until golden in hot oil in a dutch oven. Add the tomatoes and chiles. Season the sauce with salt, pepper, and oregano. Add 2 cups reserved chicken stock. Boil 5 minutes, add mashed garlic, and correct the seasoning. Place chicken in baking dish, pour all of the sauce over it, cover, and bake in a 180ºC oven for 15 minutes, until bubbly.
