Coincidently enough I was thinking of Camp coffee when people were talking about being introduced to coffee as a child.

This blend of sugar, water, 4% coffee essence and 26% chicory was what passed as coffee in our post war home.

I prefer to remember it with the nostalgia of time rather than the taste but it can still be found on baking aisles in supermarkets as it is used as an ingredient in coffee cake etc.
