Is there something you eat in the backcountry that you don’t eat otherwise?

… and Payday Bars. I never have a craving for them when I'm home but I'll destroy a Payday bar in the back 40.

I do almost entirely fresh cooking at home, so anything pre-packaged dried or instant is different for me. Most candy and junk food I do not like, and so those don't come on the trail either. The stuff I do like I also eat at home; no weird on-trail cravings. I watched Skurka's videos about his Alaska Yukon trip and saw all the neat, precisely measured bags of junk food and…while I'd eat that stuff if I were hungry enough, the thought of deliberately planning an expedition menu around pringles and m&ms makes me vaguely ill.

Peanut butter & jelly sandwiches.. I'm not a big fan usually but on a backpacking trip I'll eat whatever I feel is needed.

Also beef jerky, candy/energy bars and hot chocolate packets filled with chemicals and high fructose corn syrup; items I tend to avoid nowadays. It feels good to indulge in 'nasties' couple of times a year.

Never touch 'em at home, but in the woods, with crackers… oh yeah.
