Start by measuring out all the ingredients.

In a mixing bowl, combine the soy sauce, honey, rice vinegar, and sesame oil. Whisk until well blended.

Add the minced garlic and grated ginger to the mixture.

If you want a thicker sauce, mix the cornstarch and water in a small bowl until smooth.

Pour the sauce mixture into a small saucepan. Heat over medium heat, stirring occasionally.

If using cornstarch, add it to the saucepan once the sauce starts to simmer. Stir continuously until the sauce thickens, about 2-3 minutes.

Give the sauce a taste and adjust the sweetness or saltiness if needed.

Remove the sauce from heat and let it cool. Store in an airtight container in the refrigerator for up to a week.
