In a large stock pot, heat oil and then add the beef shanks. Sear both sides.
1 tbsp Oil, 3 lbs Beef Shanks with bone
Add the pieces of onion, peppercorns, and fish sauce. Sauté for one minute.
1 tbsp Whole Peppercorns, 1 whole Large Yellow Onion, 1½ tbsp Fish Sauce
Add the extra marrow bones.
1 lb Marrow Bones
Fill the pot with water, enough to cover the ingredients. I used 2 liters for this recipe but adjust to the need. Add the additional vegetable broth. Everything needs to be totally submerged. Bring it to a boil.
2 liters Water, 4 cups Vegetable Broth
Once it starts boiling, skim off anything that rises to the surface using the soup skimmer. This will help keep the stock clear. Skim the stock many times throughout the entire cooking time in order to have a clear broth.
Reduce the heat to low and let it LOW simmer for 2.5 to 3 hours, or until the beef is fork tender.
Keep skimming the soup. Once the beef is tender, add salt and pepper to taste.Remove the onions with the skimmer if you prefer a more refined bone stock. 1 tsp Salt, 1 tsp Ground Black Pepper
Add the potatoes.
4 Small Potatoes
Towards the end add the corn. Add the green cabbage last.
3 Corn, ½ whole Green Cabbage
Ladle the Bulalo into large bowls, making sure to include stock, beef shanks, corn, cabbage, and any other veggie in each serving. Garnish with scallions. 1 small bunch Green Scallions
