Add the tamari and arrowroot starch to a small bowl. Whisk until the starch has dissolved.
Add the remaining ingredients and whisk to combine. Use immediately in a stir fry recipe or transfer the homemade sauce to a mason jar or airtight container for later use. Store in the refrigerator if not utilized right away.
Notes
To store: Keep in the refrigerator for up to one week. Shake before use as ingredients will separate. This recipe makes approximately ¾ cup of sauce which will serve approximately 4 people when mixed with veggies and protein. To use sauce: Add to veggies and/or protein towards the end of cooking. Allow it to simmer for 3-4 minutes to warm and thicken. This simple sauce is easily customizable; add a bit of fresh ginger or ginger powder, swap in toasted sesame oil for regular, add a little onion powder, or even a touch of hot sauce for additional heat.
