There are many different ways that you can add new flavors to soy sauce. One of our favorite ways to spice it up is by combining it with minced ginger, like how we did in this recipe. We also add a bit of sugar to help the sauce thicken once it's reduced, as well as a bit of sesame oil for the perfect drizzle. Some other ways to flavor up soy sauce are adding spices and seasonings like garlic, chili powder, or even cinnamon. You can combine it with creamy peanut butter to make a delicious peanut sauce. Get creative and try it with your favorite spice combinations!
