My daughter's class is going on a camping trip & I have been asked to make pancakes for the third morning of the trip for 30 people. The pickle is how can we make so many pancakes that can be served close to simultaneously? We've considered premixing the pancakes, but then how do we cook enough at once? We've considered cooking them in advance and freezing them, but then how do we reheat? Any other possible options or tried & true recipes?
