What is that? I need to buy it!

I have been spending a lot of time in the produce section of the grocery store since I have started counting calories.  I'm always looking for things to fill my belly that have a low calorie cost.  And that I don't mind eating.  Which isn't always easy.  All this time looking at fruit has made me aware of a strange impulse I have to buy things when I don't know what they are.  If there is a fruit that I have never seen before I tend to buy it.  You would have thought I would have learned not to do this since the first time I did I ended up with a Buddha's Hand.  I had no idea what it was or how to eat it but it was new and looked cool.  Turns out, you don't really eat a Buddha's Hand because there is nothing there but skin and pith.  All you can do with it is use it for decoration or zest it.  So it sat around until it started to rot and ended up in the compost.  But I keep going.  Recently I was picking up some mangoes and saw something new.  "Oh, what's that?  I need to buy it."  So in the cart it went.  This time it was kiwi berries.  Which turned out to taste like a mix between a kiwi and a grape.  This compulsion came as a surprise to me since it is the only place in my life that I am adventurous.  I usually don't like new and am not impulsive.  Unfortunately, this is a lose-lose type of thing.  On the one hand it could turn out to be something I don't like.  On the other hand I could like it but since I have never seen any of these odd fruits twice I can never get them again.  But at least I'm expanding my horizons so I can recognize more things when I'm watching Chopped.
