Sometimes what I crave isn't the thing itself but the sauce that goes with it. Years ago when I was a vegetarian, I did very well without eating meat except for a recurring craving for hot dogs. I couldn't go to a Dodger's game or a county fair without being taunted by the sight of a hot dog stand.
Even now, writing this, my mouth waters at the thought. In time I realized it wasn't actually the hot dog that I missed, it was the mustard, relish, and chopped onions that had me questioning my commitment to vegetarianism.
I have to confess to a lack of enthusiasm for fish. Over the years I have found appetizing ways to prepare salmon, sand dabs, tuna, and sole, but fish isn't my "meat" of choice.
