This Silpain ( Silpat for bread) is a must when making dough and baking bread rolls, buns and more. This 11-5/8 x 16-1/2-inch mat will turn your pan into a non-stick surface. The mat is a flexible, non-stick, easy-to-use liner that has a perforated texture covered with food grade silicone and can be used thousands of times. It is ideal for freezing and for baking bread of all shapes and sizes, which are not required to be calibrated, as well as for the partial baking of tarts. The mat must be used flat and placed on a tray (we recommend a perforated tray as this provides better heat circulation). The mat is easily cleaned using a soft sponge under running water. Nothing sticks to Silpat, so it will save you a lot of time cleaning as there in no more sticky mess on your pans! Silpat never needs greasing, which saves both time and money. Use Silpat instead for any baking recipe that calls for parchment paper. This saves money and creates less waste for our environment. Life of product varies-lasts 2,000 to 3,000 uses depending on use and care. Can be used at temperatures varying from -40 Degree to 250 Degree (-40 Degree to 500 Degree). Made in France. Silpat is known around the world as the original non-stick baking liner. Silpat liners are made of fiberglass and food grade silicone and are completely food safe. Nothing sticks to Silpat! Sasa Demarle Inc. was founded in 1965 by M. Guy Demarle in Northern France. Mr. Demarle was an experienced baker who was seeking a better way to make baguette bread with forms using non-stick silicone coatings. He went on to invent the first non-stick baguette baking trays or filets, as they are known in France. A few years later, Mr. Demarle also went on to invent and create the original Silpat. Since then, we continue to strive for improvements in non-stick products for the baking, patisserie and food-service industries.
