Thinking way back to my first camping experiences, I remember "blackened pancakes with white gas syrup" coffee grounds with a touch of water (yes, even as a very young child I was hopped up on the bean), plenty of trail mix, and home-packed tubes of crema de cacahuete y mermelada. My dad always packed a ziplock bag of cornmeal and garlic to fry fish in as well, and this item is now typically found in my kit.
Just thinking about those terrible pancakes and coffee makes me want to go camping right now. :coffeedrink:
Thought of another one from some of my first "no parents" camping: Bisquick and a tiny bit of water. Make a really thick dough, wrap it around a stick, hold/rotate over fire. Outcome: "campfire bread"... mmmmm (well, at least when you're a kid it's good)
