A recent exchange with a co-staff on trail:
Me: "Hey, I think your apple's in the fire."
Jesse: "Yea, I put it there."
Me: "Oh. Why would you do that?"
Jesse: "I'm roasting it."
Hmmm...very interesting concept. Literally he just tossed his apple on the hot coals and about an hour later sliced up a perfectly baked, juicy, warm apple to share with us. It tasted just like the baked apples that my mom made in the oven when I was a kid for an after-school snack. No foil required. Just make sure it doesn't get in the flames, and keep turning it to cook it evenly. Dust off the ash and voila! Cozy comfort food.
