Cut off the small piece of the chicken wing and the bony part so you have
only the meaty part. (but
the bony part is good also.)
Mix the ketchup, onion (cut up), brown sugar and sauce together.
Dip wings in the sauce.
Put on cookie sheet.
Bake at 350 degrees for about 1 1/2 hour.
If you have extra sauce, cook in saucepan until thick.
