BBcue-Z, and Airfoils..I had never heard of holes in burgers until I read about them on another post, and reading about them. Actually I thought it was kind of a novelty thing. One day, my wife and I were at a Costco (we belong to Sam's Club), and I saw pre-formed burgers with the hole in them. I figured that I must have really been in the dark on this one. Everything you guys said makes a lot of sense.
