Or do the producers just fear repetition and are scraping the barrel casting too big a net to come up with themes? And have the competitors been briefed that 'traditional' flavours and combinations will be marked down? Hmmm. off to console myself and bake some garlic and petroleum shortbread
I've wondered the same - personally, repetition wouldn't bother me. I'm always so impressed with the skill and ingenuity whatever the challenge is.
Was your shortbread nice?
