Backpacking is energy intensive. It is essential enough food is taken to maintain both energy and health. As with gear, weight is critical. Consequently, items with high food energy, long shelf life, and low mass and volume deliver the most utility. "Satisfaction" is another consideration, of greater or lesser importance to all hikers. Only they can decide whether it's worth the effort (and trade-off against other gear) to carry fresh, heavy, or luxury food items. The shorter the trip and easier the conditions the more feasible such treats become.
