Add bones, water, beef shank, pork hock, lemongrass, pineapple, onion, shrimp paste, salt, and sugar and bring to boil. With a fine mesh strainer occasionally remove any gunk that rises to the top. Then reduce the heat to lowest setting to simmer. The pork hocks should take about 45 min-1 hr to cook--when the skin is tender, remove and set aside. The 3lbs of beef shank takes roughly 3 hrs to cook. To see if the beef shank is cooked, poke a chopstick into the center, it should slide in with minimal pressure. If there is no blood oozing out, then it's done. Remove shank and place in water bath to avoid discoloration and set aside to cool until ready to slice.
