Choose trail recipes that use dried ingredients like powdered milk. Mix these ingredients ahead of time, in the proper number of servings, and store them in a zip-lock plastic bag. On the trail, add water, then mix in the bag. Take some tortillas. They're a great way to roll up dinner and eat.
Cooking is a matter of choice and safety.
Empty cartridges must be disposed of properly. Stoves must be primed before starting. Excellent for grilling. Small grill also provides container for wood fires. A campfire in the morning and before bed are part of the trail ride experience.
