I discoverd this stuff in the Yorkshire Dales in 1977. Romney's brown sugar version was my favorite then and still is. It never fails to give me a boost, especially when the weather is grim. On an unexpected overnight bivvy last year it was a big hit when I dug out a bar, especially since there was little actual food between four of us. I always liked the little note on the back of the wrapper recalling the 1953 Eversest Expedition;
"We sat on the snow and looked at the country far below us ... we nibbled Kendal Mint cake" "It was easily the most popular item on our high altitude ration - our only criticism was that we did not have enough of it"
