Round egg noodles are ladled into a pork-and-shrimp broth loaded with sliced pork organs, beef, and crushed pork cracklings, then topped with fried garlic and a raw egg cracked in tableside. Iloilo City's La Paz Public Market is the dish's spiritual home, with several competing stalls each claiming the original recipe.
