I decided instead of buying tahini butter I would just purchase sesame seeds and grind them up to make my own tahini (for my salad dressings). Well I did this today and the my dressing turned out bitter tasting. Does anyone know why? I would rather make my own tahini then buy it-but I don't want the bitter taste (and I want to save some money<img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/redface.gif" style="border:0px solid;" title="Embarrassment"> ). Any insight welcomed.
