On trips I lead, we always split up into smaller cook groups, yet I did have one occasion a long time ago where we cooked as one large cook group. Long enough that I don't remember if it worked well or not. (I don't think that it did, but we also could have done something wrong.)
On extended trips into the wilderness, whether it be backpacking, kayak trips, etc, what are the advantages of cooking together as one entire group? Conversely, what about the advantages of splitting up into smaller cook groups? Would the type of trip, and environment be a factor in the advantages?
Let's say we have a group size of 9 people, and the trip is 10 days, no resupplies, and it is a temperate, forested environment.
