To make the pork ribs tender: In a pot, boil (submerged) pork ribs in water with the bay leaf, cloves (spice), chili and 1/4 pork broth cube for 30 minutes. Note: the traditional way is letting it sit in the soya sauce for more than an hour, which is just too long for me! (: hehe

Lower heat to simmering point. Drain most of the broth, leave about 1/2 a cup in the pot with the pork. Remove the cloves and bay leaf. You can set aside/freeze the broth and use this as side soup or base for another dish.

Crush garlic cloves, peel and tear apart; then drop it in the remaining broth in the pot with the pork. Scatter it around.

Add the soy sauce, worcestershire, oyster sauce and red wine vinegar (add directly to the broth area) without mixing it. DONT mix/stir, just cover the pot and let the red wine vinegar cook off.
