I'm doing the Tai Bwo Wannai Trio quest and CANNOT seem to cook the karambwana so it is poisoned. Whether I cook it on a range or a fire it does not give me the option to cook for a "short time" or "partially" cook it. It either cooks as edible or burnt. My cooking level is 67. I can't figure this out for the life of me, I desperately need your help.

well I think you must finish the quest before you get the oprion to cook it (poorly) then you should be able to get the poison.. also remember the poison only works on spears :|

I think it was so that if you're level 65 it gets cooked properly...
