I have previously written about my desire for a silpat. As they are unavailable in Australia I have considered purchasing them from eBay USA and paying the exorbitant shipping... but I was pleasantly surprised to find Nordicware's baking mat. It's weird, and I don't know what it is made of. But the deal is that it comes in a large rectangle which you can cut to size - and there are templates for Nordicware's baking trays if you have one to match your baking mat!
So far I have only used it instead of flouring my bench - because I have plenty of baking paper to use up first!
