PINEAPPLE BROTH: Drain all juice from canned pineapple (no actual pineapple yet) into small bowl. Add broth until there is enough liquid to fill one cup combined.
TERIYAKI SAUCE: After making pineapple/juice broth mixture, combine first 6 ingredients in small sauce pan. In separate cup, combine cornstarch and water (COLD) and mix thoroughly. Set cornstarch and water mixture aside. Heat ingredients in sauce pan over high heat, stirring occasionally to keep the bottom from burning. Just prior to boiling point, slowly add the corstarch and water while stirring CONSTANTLY. Mixture in pan will start to thicken. When desired consistency is reached, add pineapple chuncks. Let cool, then serve.
