I always bring a big tub of honey, in the plastic dispenser I buy it in. Good with lots of things, including snow, and it can just go back up on the shelf when you return. Chocolates, I'm afraid, would never make it back to the shelf. They would be lucky to make it to the trailhead.

Speaking of which. Bacon. I like a bacon and eggs breakfast at a truckstop before the trailhead. I am going to bring a pound of bacon with me on a trip this winter also, and maybe do something with the leftover bacon fat, like biscuits, or just drink it straight up. lol
