Bulalo is a delicious Filipino dish that is known for its rich and flavorful broth. It is typically made by slow-cooking beef shanks and bone marrow, along with various vegetables like cabbage, corn, and onions.
In a large pot, add the beef shanks and bone marrow (if using) and cover with water. Bring it to a boil and skim off any impurities that rise to the surface.
Add the sliced onion, minced garlic, fish sauce, and whole black peppercorns to the pot. Stir well to combine.
Reduce the heat to low and let the broth simmer for about 2 to 3 hours, or until the beef is tender and the flavors have melded together.
Once the beef is tender, add the corn and cabbage to the pot. Let them cook for about 10 to 15 minutes, or until they are tender but still slightly crisp.
Season with salt to taste.
Serve the Bulalo hot, garnished with chopped spring onions.
