Mince the fresh garlic and ginger before starting so everything mixes smoothly.
In a medium bowl or mason jar, combine chicken broth, soy sauce, honey, sesame oil, ginger, garlic, and cornstarch.
Whisk well or shake the sealed jar until the cornstarch fully dissolves and no lumps remain.
Add optional crushed red pepper flakes, sriracha, or sweet chili sauce if you want extra heat.
Use the sauce immediately or refrigerate in an airtight container for up to 1 week.
To use in stir fry, heat 1 tablespoon oil in a skillet or wok over medium-high heat and cook 1 pound of protein until lightly browned. Remove from pan.
Add another tablespoon of oil and cook about 6 cups of chopped vegetables until tender-crisp.
Return protein to the pan and stir the sauce once more before pouring it in.
Cook for 2 to 3 minutes while stirring until the sauce becomes thick and glossy enough to coat the ingredients.
Serve immediately over rice, noodles, or cauliflower rice. Garnish with sesame seeds or green onions if desired.
