Camping with a pack-it-in, pack-it-out mentality doesn’t mean you waste food. Parmesan rinds? Toss them in your camp soup pot for a savory boost. Orange peels or cinnamon sticks? Simmer with water for a makeshift bug-repelling “camp potpourri.” Got bacon grease? Use it to fry tomorrow’s breakfast. Saving and reusing scraps adds flavor and stretches your supplies — which means less to carry and more to enjoy.
