I'm thinking about trying something different next time. We have a collapseable cooler that I am going to fill with tupperwares full of frozen entrees that I make ahead of time. We'll be staying in a studio, so we won't have the stove and oven. I think this will work, and we can even check the cooler since everything in it will be frozen, and you can't break a collapseable cooler!
I'm also thinking of trying out the grills for the first time. I guess they're not gas grills? Wishful thinking.... I don't know if I know HOW to light charcoal!
Rich, most broths will gel up like that when they're cold. Have you tried cold chicken broth? It might be better than the pig's feet! BTW, I buy pigs feet to use as flavoring when I make soup that's going to simmer all day. But then I throw the pig's feet away and eat my soup HOT.
