Place the first 8 ingredients in a small bowl and whisk to combine.
Place the oil in a large skillet or wok set over medium-high heat. When hot, add the prawns and cook 1 minute per side. Add the honey mixture, bring to a simmer, and cook 1 to 2 minutes more, or until the prawns are nicely glazed and cooked through. Sprinkle prawns with mint or cilantro and serve.
Note: To devein the prawns, use a small paring knife to make a lengthwise slit along the back of each peeled prawn. Pull out, or rinse out with cold water, the dark vein. Pat prawns dry and they are ready to use.
