at my local organic grocer, tahini is available in bulk. i wanted to buy some, but it tasted unlike what i am used to (which is tahini from a can). if i buy it in bulk, what must be added to make it taste like what i'm used to? i thought it was supposed to be creamy, white-ish and somewhat tangy. this was thick, brown and tasted like thick toasted sesame butter (which i suppose in essence it is).
