Add in the 1 pound of brown sugar and 16 oz of cooking sherry.
Stir until brown sugar dissolves.
Add in 1 1/2 cups of soy sauce, then stir.
Once the brown sugar and liquids are combined, add in the frozen chicken wings. Then stir.
Let the stockpot sit (uncovered) for 90 minutes total. But be sure to stir every 10 to 15 minutes making sure to pull the bottom layer of chicken wings to the top so they cook evenly.
