I had a sainsburys cast iron cassarole pot that gave up the ghost after a few years, whilst my hand me down Le Creusets are still going strong, only problem is they are too small for certain dishes. Given that a 6/7 litre Le creuset is stupid money I have been considering a more tradional ducth oven without legs. I know that these are not enamel coated. I just wondered if anyone has any experience/recommendations regard using a tradional dutch oven on a gas cooker for long cooking periods?
