Mark: "I'm going for dark green marzipan. So I'm doing a turkish bazaar inspired Battenberg. Me and my wife both love Istanbul. It's actually my wedding anniversary today, so I thought it's actually worked out quite a good time to do the battenberg."

Beneath Mark's green marzipan were Turkish flavors of orange, pistachio, cardamom and pomegranate. 

Judging

Prue Leith: "It's a nice, light sponge. I think it's a little thick, but I like marzipan."

Paul Hollywood: "Pomegranates don't do anything, flavour wise. It's pistachio in the green sponge and that brings a lovely texture to it. "
