Jacques Torres's Chocolate Leather
Follow this technique using dark or milk chocolate to create thin, flexible sheets of chocolate perfect for wrapping around the edges of a cake or creating other decorative details. Jacques Torres prepared this recipe with Martha on Episode 501 of "Martha Bakes."
You can substitute a 12" X 12" marble tile, but you will only be able to create pieces of "leather" with those dimensions.
If you work too slowly it will stick and become harder to remove. If your "leather" tears, just add it back to the bowl of chocolate to reuse and melt again.
