Does anyone remember a packet fudge mix available in the U.K. in the late 1970s early 1980s? It came in a box, with a cardboard tray to pour your made fudge into - in vanilla or butterscotch flavours. I seem to remember you added a measure of milk and heated for required minutes in a saucepan. It was delicious and easy to make. Does anyone remember who manufactured it please?
