Cooks Tips

To make the feather icing pattern, use almost all the glace icing to cover slice. Colour remainder with cocoa. Turn into a piping bag with a fine, plain nozle. Pipe lines down the slice about 2.5cm apart. Drag a wetted, warm skewer across the icing at right angles to the piped lines. Drag first one way, then the other.
