Pastry mats are sheets (usually made out of silicone) which are used for rolling out dough. Although they can be bought plain, the most useful sorts are those which have conversion charts, measurements and circle guides. These silicone baking mats are reusable.
The Bake-O-Glide mat is made from non-slip silicone and is suitable for rolling out all forms of pastry, marzipan, fondant icing, and is also suitable for chocolate work and kneading dough. It is easy to clean, is dishwasher and oven proof and comes with a storage tube. It measures 42cm x 61cm. Kitchen Craft produces a less expensive alternative.
Silicone rubber is Highly inflammable
Although silicone baking mats are heat resistant to at least 500°, they are also highly inflammable and will catch fire easily if directly exposed to flame or if they a come into direct contact with an oven heating element. Once burning they are difficult to extinguish as they can re-ignite easily.
Be careful; do not allow any loose edges to hang over pans or oven trays where they can come into contact with a heat source. If there is a surplus area, fold the mat on itself or even cut it to shape.
