Set up your Weber Kettle for indirect smoking – Fill your charcoal chimney fire starter with charcoal briquettes, and when ready, empty the chimney in the center of the charcoal grate. With tongs, move the charcoal to both sides of the Weber Kettle, creating two equal piles. Add three more charcoal briquets to each pile.
Bring the chicken wings to room temperature – Pat the chicken wings dry with a paper towel. Combine the chicken wing rub with the cornstarch in a medium-sized bowl. Sprinkle each chicken wing with the chicken wing rub, ensuring the entire chicken wing is completely covered with the rub.
Place the chicken wings on the Weber Kettle grill grate – Place the chicken wings in the center of the Weber Kettle grill grate and grill indirectly for 20 minutes, then flip the chicken wings over and grill indirectly for another 20 minutes. Rotate the chicken wings away from the heat of the coals if necessary. Add more charcoal to both piles if necessary as well.
As the chicken wings are grilling, make the Buffalo chicken wing sauce – Combine all the Buffalo chicken wing sauce ingredients in a medium-sized saucepan and, while stirring with a whisk, bring to a low simmer.
Move the chicken wings over the charcoal pile for extra char –
With grill tongs, move the chicken wings to the sides of the Weber Kettle grill grate for direct grilling. This will complete the grilling of the chicken wings and add a nice char-finishing flavor. This step should take about a minute a side. Watch the chicken wings carefully, as you don’t want to burn your precious hard-earned yumminess.
Remove the chicken wings and add the Buffalo hot sauce – Place the Buffalo chicken wing hot sauce in a large bowl. While both the Buffalo chicken wing hot sauce and the grilled chicken wings are still warm, add the chicken wings to the Buffalo sauce about five at a time. Thoroughly submerge and mix the chicken wings with the Buffalo sauce until the chicken wings are completely covered in the Buffalo sauce. Repeat this process until all the chicken wings are covered with the Buffalo sauce.
