Cut pork roast into 1 inch cubes, trimming and discarding any big pieces of fat. Add to a large stock pot with enough water to cover the meat by around 2 inches (8-10 cups water). Bring pot to a boil. Skim off any foam that rises to the surface.

Add to the pot one quartered onion, 5 whole garlic cloves, bay leaves, 2 teaspoons salt and chicken bouillon and simmer for 1 1/2 hours.

Meanwhile, remove seeds and veins from chilies and add to a small pot with enough water to cover them. Bring to a boil and boil for 15 minutes. Remove from heat.

Use a slotted spoon to spoon the chilies into a blender. Add 1 cup liquid rom the saucepan that boiled them, along with 5 peeled garlic cloves. Blend well until smooth.

Discard any remaining water from the small saucepan that cooked the chilies. Add 2 tablespoons oil to it over medium heat. Pour the blended chilies mixture through a fine mesh strainer into the pot and cook for 10 minutes over medium low heat, stirring often.

From the stockpot with the meat, remove bay leaves, onion, garlic cloves, and neck bones (if used). Pour in the chili sauce mixture, tomato sauce, oregano, cumin, white vinegar, and hominy. Season with salt and pepper to taste. Bring to a slow boil and then simmer for 30 minutes, or until pork is very tender.

Taste and adjust seasonings (add more salt, chicken bouillon paste or oregano, to taste).

The toppings added really make or break the soups end result! Ladle soup into bowl and top with a handful of shredded cabbage, chopped onion, fresh cilantro, and a squeeze of fresh lime juice. You could also top with avocado and thinly sliced radishes. Serve with a tortilla on the side.
