This soup is sour, and yes, that's a good thing. My family, like most Filipino families, make this soup using a store-bought sour mix that comes in a little packet. I left that packet back at the market and instead, used ample amounts of tamarind concentrate. (Visit our Filipino Pantry list for more info on tamarind.) I've also included citric acid crystals to really pack a sour punch. Your grocery store may carry this in the canning aisle, if not, the internet does. As for the spareribs, if you can only find them uncut, the meat counter will be happy to prep them for you.
