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.
Warning: For all of the methods in this post, make sure you gather the rocks from a high and dry location, as waterlogged rocks can explode dangerously when they heat up in a fire. The steam builds pressure in the rock causing it to blow up like a grenade. Also, avoid slate and shale, as they are prone to explosion regardless of where you find them….”
