In the marzipan for her chocolate orange Battenberg, orange liqueur wasn't the only surprising ingredient. There was also marmalade in it, in the place of eggs.

Judging 

Prue Leith: "That looks really pretty. 

Paul Hollywood: "I like the decoration. I like the fact that you've glazed it as well, because that, again, sets it off. All the flavors are there."

Prue Leith: "I think the texture is very good. It's very neat. I like the marzipan. Individual elements are good, including the buttercream. I think it's a lovely piece of cake. "
