Rice paper is a thin, edible type of paper that can be used to transfer pictures and other designs onto cake. Unlike regular paper, designs are not printed directly onto the rice paper. This edible paper is used to trace a printed image. Then, bakers use the edible rice paper as a guide line for drawing an image with icing or piping gel. Purchase rice paper and piping gel from a local baking supply store or Internet retailer. Be sure to purchase extra product and reserve time to practice tracing designs.
Place the printed image face up on the table. Cover it with a piece of rice paper, rough side down. Use a non-toxic crayon or pen to trace the image on to the rice paper. Do not press too hard or the rice paper may tear.
Use scissors to cut out the rice paper carefully. Stay as close to the edge of the design as possible.
Cover the rough side of the rice paper with clear piping gel. Place the piping gel on top of the frosted cake.
Fill a pastry bag with dark coloured icing or piping gel. Fit a small, rounded writing tip to the edge of the pastry bag. Practice piping icing on a piece of paper or cardboard until you fill comfortable drawing thin lines. Use the dark icing to trace the outline of the design.
Fill an additional pastry bag with coloured icing matching the ideal colour for the small, detailed areas of the image. Fit a star tip on the bag and fill in the small, detailed areas of the image. Move from the smallest, most detailed images to the largest images. Be sure to use a new pastry bag filled with the icing in the corresponding colour.
