The purchase of a cast iron Dutch Oven is an investment that, with proper care and use, increases the adaptability of heating options that will last longer than my lifetime! Keengardner's range of 'Napoleon' cast iron goods - at excellent prices - are worth a look. I have already cooked baked potatoes with the oven directly on the top of a gas stove - the economy is phenomenal compared with firing up an electric oven. I am just building up a sourdough starter so I can cook a full-sized loaf in the Dutch Oven - using overnight cheaper electricity - in the (upturned) Dutch Oven. The way it traps moisture enhances the silkiness of baked potatoes - and the deliciousness of sourdough bread can't be believed! So buy your Dutch Oven from Keengardner - at a good price - and you'll increase the range of healthy food - whilst increasing your fuel options! Just remember to 'oil' the cast iron after every use - and it will outlive you.
