I used a larger can of pinapple, added a little more soy sauce, cornstarch and brown sugar to compensate. I did not add more vineger because it seemed like plenty. I also added a little garlic salt to the meatballs. I served it over white rice. I could not figure out if the recipe was saying to add the fat from the skillet to the sauce or not. I added a little of it, but I had used oil, not shortening. All in all the dish is okay. I would eat it again, but may try to tweek it even more. Oh I also used fresh minced white onion.
