Combine Ingredients: In a small saucepan, mix 1/2 cup of soy sauce, 1/4 cup of honey, 1 tablespoon of rice vinegar, 1 teaspoon of minced garlic, and 1 teaspoon of grated ginger.
Simmer the Sauce: Place the saucepan over medium heat and bring the mixture to a simmer. Stir occasionally and cook for 3-4 minutes, allowing the flavors to meld together.
Thicken the Sauce: In a small bowl, mix 1 tablespoon of cornstarch with 2 tablespoons of water to create a slurry. Slowly add this slurry to the simmering sauce while stirring constantly. Continue to cook for another 2-3 minutes, or until the sauce thickens to your desired consistency.
Cool and Use: Remove the saucepan from the heat and let the sauce cool slightly. Use immediately as a marinade, glaze, or dipping sauce, or store it in an airtight container in the refrigerator for up to one week.
