Rainbow Icing Instructions

  1. Separate the icing into 6 small bowls.
  2. Add food colouring to each to make the colours of the rainbow (red, blue, yellow, orange (red+yellow), green (yellow+blue), and purple (blue+red).
  3. Place the contents of each bowl into a separate piping bag and snip the ends.
  4. Lay a piece of plastic wrap on the counter and pipe a line of each colour right beside each other, in the order of the rainbow (red, orange, yellow, green, blue, purple).  Leave at least 2” of plastic wrap at each end of the piped lines.
