I put abit of baking soda and sugar in with my tares, its supposed to give em a darker sheen and makes the skins a bit more rubbery.
Ive put all sorts of crap in with hemp before, tumeric,chilli,five spice etc etc.
cant realy say wether it does any good or not! , it makes the kitchen smell a bit better though!
like you say Colin, if your happy with what your doing stick to it
