Chicken wings are usually sold in two ways at the grocery store: “party wings” or whole wings. The party wings are already broken down into drumettes (which look like mini drumsticks) and wingettes (also called flats). The whole chicken wings are sold with the drumettes, wingettes/flats, and wing tip still connected.
Lay your chicken wing skin side down and locate the 3 parts: drumette, wingette (or flat), and wing tip, and find the joints between them.
Place your knife cutting through the “V” that the joint makes, and cut through the joint cartilage by pressing the heel end of your knife firmly and straight down.
Repeat for the joint between the flat and the tip. The knife should easily cut through the joint and the bones will stay intact.
Now you have the wing broken down into flats and drumettes. You can discard the wing tip, or save for stock. Repeat for all the wings
