In a small pot whisk soy sauce, water, and cornstarch together until smooth. Add any of the optional additional ingredients you are using (vinegar, garlic, ginger, etc).

Heat over medium-high heat until warm and then whisk in honey until dissolved.

Bring to a boil. Reduce heat to medium and whisk constantly until desired thickness is reached. Do not leave unattended it thickens quickly once it gets boiling and will rapidly burn.

Taste and adjust as desired. If too thick, thin with additional water to desired consistency.
