Intrigued and actually quite sceptical that a piece of toast between two slices of bread could be 'surprisingly nice to eat', I made one myself.
It was incredibly easy to make, of course - and took a couple of minutes. But once you give it a good grinding of pepper and a sprinkle of salt and layer the buttered bread over the top, the fun ends there. It was stodgy, fairly tasteless and there wasn't really any moisture at all so it tasted really dry. The only good thing about it was that it reminded me of a chip butty - but only because the semi-melted butter oozes onto the soft bread on the outside, in the same way as a warm chip sandwich does.
So at the risk of being a party pooper, I'm sorry, but there are some things that should stay in the Victorian era, and the toast sandwich is one of them. Sorry, folks.
