Preheat the oven to 500°. Line a large baking sheet with foil and spray with vegetable oil. In a bowl, mix the flour with the salt, garlic, onion and thyme. Add the chicken and toss to coat. Spread the chicken on the baking sheet in a single layer and spray with vegetable oil. Roast the chicken for 45 minutes, turning once or twice, until browned and crispy.
In a bowl, whisk the hot sauce with the butter and jerk paste until combined. Add the chicken wings to the sauce and toss.
