I can finally be my favorite Doctor's companion! I don't want to say which one. That would be rude. Rude and not ginger.
I love a repeating pattern, especially on food. Even better when it's done with something as delicious and natural as blueberries. Nothing fussy, no artificial coloring or hours slaving over perfectly smooth icing, just a fantastic and undoubtedly delicious polka dotted tower of celebration. I'll toast to that!
