Bejaysus, my downfall is that I can't judge seasoning in my finished dishes, soups, stews, ragus, anything. Even after three or four tasting goes I usually get it wrong (typically, not enough salt). I don't like salt that much but I don't want anyone else to suffer! I think the golden rule when it comes to oranges/clems/tangerines is to never try to eat them after something sweet...
