Begin by rinsing the chicken wing pieces, drain, and place them in a large bowl.
In a small mixing bowl combine your fish sauce and soy or tamari sauce.
Transfer sauces to the large bowl pouring over wings and squeeze ⅓ of large lime into the bowl.
Toss repeatedly until well coated and place in refrigerator.
Allow to marinate 1-hour tossing occasionally to coat with marinade.
15 - 30 minutes prior to cooking (depending on your oven time to fully pre-heat) adjust the oven rack to the upper-middle position and preheat the oven to 450° F.
Line baking sheet with aluminum foil and place a heat-proof food rack on top of the foil.
In a small bowl combine baking powder and baking soda. Toss to mix and then add PB2 and continue tossing with a fork until well distributed.
Place wings in wire colander to drain. Make sure to drain well, they should not be dripping.
Place dry mixture in a bag for coating adding a few chicken pieces at a time to coat evenly.
Arrange coated wings on the wire rack leaving space between wings and place in your hot pre-heated oven.
Bake 30 minutes and then turn, cooking another 30 minutes until slightly browned and crispy.
Serve immediately
Mix dipping sauce ingredients together in a small serving bowl, if desired.
