Hot stones have been used for cooking for thousands of years. Three of my favorite rock-cooking methods are frying, boiling, and stir fry. The upside to these methods is that they don’t require a lot of materials from home. Most or all of the gear for these low-tech culinary techniques can be sourced in the field. If you’re a careful cook, you’ll even make some meals that taste good. Seriously, this is nowhere near as nasty as you would think.
