1 (6oz) can pineapple juice
1 (8oz) can pineapple chunks (or crushed, diced etc)
1 Cup chicken broth (or just water)
1/4 Cup light brown sugar
1/4 Cup wine (or Cider) vinegar
2 Tablespoons Ketchup
Bring to a boil and thicken with corn starch, taste and season with salt and white pepper.
You could also replace the broth with the juice from Maraschino cherries but reduce the sugar to make up for the extra sugar from the cherries
