Preheat oven to 425 degrees. Set iton broil if you have that option.
For the wings, clean and pat them dry. Season them with salt, pepper and chili powder.
Set onto a lightly oiled baking sheet and cook for 45-50 minutes, flipping once about half way through. Keep an eye on them to make sure the skins get nice and crispy.
While the wings are cooking, make your sauce!
Start by adding the chopped peppers, garlic and peanuts to a food processor and process to form a paste. OR! If you’re like me, use your molcajete and do it by hand.
Scoop the paste into a small sauce pot and add a teaspoon of oil. Heat to medium and cook the paste about 5 minutes, stirring often.
Add chicken stock, soy sauce and fish sauce. Stir and reduce heat to low and allow to simmer.
At this point, you can add in some peanut butter, if desired. The sauce will be fairly thin and that is OK, but you might want it thicker. In that case, add the peanut butter and swirl to incorporate.
Simmer about 5 minutes.
Remove from heat and squeeze in a bit of lime juice. Stir.
When the wings are done, toss them with the Thai chili-peanut sauce to coat them.
Serve wings with crushed peanuts and some lime wedges.
