One of the best treats in South America is "milk jam," or dulce de leche. We bought a pouch of this caramel-like substance and took it on our hikes. It lasted a total of 18 hiking days, and that's not for lack of eating the stuff! It was great on apples, bananas, crackers, or just licked off your finger. It improved crappy chocolate and our moods. This stuff is GOLD. Good thing the Italian Centre in Edmonton stocks it!
