bread is something your supose to buy daily,keep it wraped to keep it fresh,but to stop it growing mould which is a different question,as its a living organism the fridge will retard it,the problem is the fridge speeds up the staling process.
It might seem like thread drift to ask where you can buy real white bread but its not.
Real white bread doesnt go off it just goes stale ( and when it is stale you can use it for making bread puddings, bread crumbs etc. just as we all did up to the '70s )
As to where to find real white bread ( apart from baking it yourself ) I put forward :
A small bakery ( sorry cant remember the name ) on the main street in Cashel
Please everybody post any that you have come across
I read somewhere that if you store your bread in the microwave it keeps fresher longer as its in an airtight environment. You'd need to make sure your microwave was clean inside though!
