The biting taste isn't just cosmetic. Being a member of the Crassulaceae, i=
t
has Crassulacean acid metabolism, also known as CAM photosynthesis - see:
http://en.wikipedia

.org/wiki/Crassulacean_acid_metabolism
An adaptation for dry habitats which results in the build-up of malic acid
in the leaves during the night which gives the acid taste in the morning.
Apparently they taste more benign after a day's sunbathing (their's rather
than your's!)
