Taste the sauce before you stir in the starch. Sugar and vinegar should balance each other, and the soy sauce adds only some salt. Add the starch to the boiling liquid and let it cook one more minute, and the sauce turns clear. It thickens further as it cools, so as a dip it may come off the stove thinner.
Over crispy meat with pineapple and bell pepper, it becomes sweet and sour chicken. As a dip it goes with Chinese spring rolls. If you like it hotter, cook sweet chili sauce instead.
