Why not bake your own bread when you’re camping? Baking bread on a slab of stone is bread baking Stone Age style. If you really want to create authentic northern European Stone Age bread replace the wheat grains and wheat flour in the recipe with rye grain and rye flour. The wheat had not come this far north at that time. And skip the salt and taste the bread with wild herbs that would have grown here then, for example, yarrow or nettles.
