Are these things that taste like rhubarb? That's
another plant that people use for sourness in
imitation of tart fruit. I don't know what acids are
in it, but I assume the stems have at least some of
whatever poisons you're supposed to avoid in the
leaves. I can't stand rhubarb, or sorrel either, since
even if they taste good to my tongue, they make my
teeth feel chalky. Give me fruit acids any day.
There's no shortage of sour fruits.
