1.Trim cakes. Secure large cake to largest board. Secure one 15cm cake to smaller board, top with remaining 15cm cake, joining with a little jam or ganache. Prepare cakes for covering with ready-made icing.
2.Knead ready-made icing on surface dusted with a little cornflour until icing loses its stickiness.
3.Tint half the icing pale green, roll icing on cornfloured surface until large enough to cover 20cm cake. Using rolling pin, lift icing onto cake, smooth with hands then smoothing tools. Trim icing neatly around base.
4.Use white icing to cover 15cm cake in the same way. While icing is still soft, use strip cutter to mark grooves into the icing on the top tier. Dry cakes overnight.
5.Push trimmed skewers into centre of large cake to support the top tier. Secure small cake on top of large cake.
6.To make royal icing, sift icing sugar through a fine sieve. Lightly beat the egg white into a small bowl until mixture is just broken up (do not whip into peaks). Beat in the icing sugar 1 tablespoon at a time, until it reaches desired consistency. Using a wooden spoon mix in the lemon juice.
7.Tint half the royal icing green to match the bottom tier. Three-quarters fill a piping bag with icing; pipe around base of cake. Use fingertip to blend icing into any gaps where cake joins the board (page 212). Repeat process using white royal icing for top tier. Dry cakes overnight.
8.Wrap ribbons around base of bottom cake; cut to fit. Secure ends with a little white royal icing.
9.Trim silk flower to fit top of cake. Wrap stem in white florist’s tape. Gently prise open flower petals; lay flower on top of cake.
