Does anyone remember this from the 70s? We used to buy it in Littlewoods (which was an actual shop not a catalogue) and then later, when I moved to London, in MacMarket. It was cut from a giant foil-wrapped block and was very cheap. The texture was strange, sort of fudge-like, and it didn’t completely melt when grilled. Have googled and there seems to be something similar available from Amazon etc but at a high price for a very small quantity. I have a yearning to taste it again In a resilient toastie.
