[Technical challenge: mystery box, no recipe, two hours, judged blind. Finished 11th] Shannon made a lemon drizzle cake soaked with lemon sugar syrup and finished with lemon curd and an icing drizzle, after her Swiss meringue buttercream split. Shannon: "At least I can choose what it is." Shannon: "Well, I have decided on the lemon drizzle. I've made loads with a method and ingredient list. Without that, we're on a whim." Shannon: "After what happened with my mum in the signature, I've got to be very cautious now 'cause my flavors are too strong." Shannon: "So I think I'm going to start it at 180 and see how it goes, 'cause I like my lemon drizzle to have a bit of a crisp edge. Let's do 20 minutes and see what it looks like after that." Shannon: "I just gotta remember what goes in lemon curds." Shannon: "It doesn't look too bad. So now I'm just going to poke loads of holes in it. Got a sugar syrup and drizzle that on top. Lemon drizzle." Shannon: "I think it's going to be a bit too basic. I'm potentially thinking Swiss meringue buttercream, and it might look really pretty." Shannon: "Oh, my God. It's split. My Swiss meringue buttercream has not gone well. I'm giving up with that now. I'm gonna do, like, an icing drizzle." {Shannon}: "This is lemon curd, just to give it that extra bit of [zing]." Shannon: "Not a fan of audience choices. Sorry, audience."
