Thanks Middle I've always thought they'd tasted bit like a sweet scrambled egg 
My Mum's boucakes are fab aren't they, she'd never iced a cake in her life and watched one video and tried it out and it turned out she was flipping fantastic at it although she's still convinced that every one she makes is a fluke! They're large cupcake sized cakes and I get to be chief taster so that's great for me 
Here's a few more pics
