Saku was also planning a family favourite for her vertical layer cake.  She said "I'm making lemon and blueberry vertical layer cake."

The judges asked her "Have you made it before?" and Saku replied "Yes, this is my husband's favourite cake. "

Saku's cake featured a sharp lemon cream cheese icing and blueberry buttercream. 

The judges said "Blueberry often has very pale flavour. Are you adding essence or anything to boost it up a bit?" Saku replied "I made a blueberry reduction so I am adding that to the buttercream. "

Prue Leith said "I love the idea of the flavors. They do sound very good. "
