We don't pack light and always bring a regular aluminum Dutch Oven and I'm ashamed to say we also pack in charcoal briquettes.  We decided that you need the charcoal for uniform heat sourced.  The recipe for baking in our 9" square dutch oven is 9 coals under and 12 coals on top for an even 375 degrees.  So if you see us on portages in canoe country we are the ones with the 300 pound packs.  But the advantage is we have cakes and pastry at ever meal.  German Chocolate Cake, brownies, even fresh baked bread.  We work hard and in cold  weather and I'm sure we burn thousands of calories a day and and I've gone on trips and actually gained weigh.
