If you are a coffee lover, camp is a coffee substitute made from chicory which may not suit all tastes. I prefered to make a syrup using one of the better quality coffee granules when I used to make it.
It is purely a matter of taste.
I do think that the cream liquers for £3 or £4 a bottle from Aldi, Asda etc are good enough not to bother to make them at home now.
