In a small bowl, mix together sesame oil, coriander seeds, cumin seeds, light brown sugar and fish sauce.
Place the chicken wings into a container or plastic bag, and then pour in the marinade and coat well. Cover or seal the container/bag, and refrigerate for at least a couple of hours (overnight is best).
Preheat oven to 425F.
Line a baking pan with parchment paper, and place the chicken wings on top (keep any leftover marinade for basting later). Then sprinkle with ground white pepper.
Bake for 20 minutes, then flip the chicken wings over and brush them with the remaining marinade. Bake for another 15 minutes.
While the chicken wings are roasting in the oven, prepare the hot sauce by mixing all the ingredients in a bowl.
Once the chicken wings turn crispy and golden, remove from heat and lightly brush each with the hot sauce. Garnish with lime wedges and serve immediately.
Notes
The coriander seeds and cumin seeds can be crushed using a mortar and pestle. You can replace the seeds with ground spices, but the flavors will be more subtle.
