In our troop each patrol creates the menu and the campout grubmaster does the shopping. All menus must be approved by the scoutmaster. We make sure they are actualy going to be cooking. I had an older scout that wanted to bring pre cooked food for dinner. Review of the menu and shopping list is a must. Now the patrols all have a guests for the day or weekend. We split the adults between the patrols. This gives adults a chance to make sure that they are actualy rotating the duties as listed on the dutry roster. Plus it gives us a chance to interact with the patrol while it is functioning. The boys work harder at cooking when they know that a guest will be coming to dinner.
