Sorry, I know this is off topic but thought some regular posters may be interested. I watched a YouTube video yesterday where one the vloggers took a Tunnocks teacake, put it in a brioche bun and squeezed so the teacake spread over the bun. He said it was really good so I think I’m gong to try it.
He previously did a kitkat sandwich in another video and said the Tunnocks in a bun was better!
