At the moment, my characters in Healing Stones (Castle Keepers Series: Book 4) are travelling through Yikker Wood. They left Inglenook about two weeks ago, and they won’t reach a settlement to buy supplies for another three days.
This means they must carry all their food in packs or saddle bags on their horses. They could hunt, and they may resort to that, and they’ve picked mushrooms along the way to add to their dwindling supplies.
For several days after they left Inglenook, they ate biscuits, bacon, eggs, bread and meat, but those perishable goods are gone after 14 days. This is the point where I scramble to find food for them to eat, so they won’t starve.
