Sometimes I don't like raw pears, cause they taste very bitter. Almost green. Apples can taste that way too. I think those pears come from poor soil in a certain regions. Other pears are very sweet and tasty. I have always thought that prunes can be too bitter or too sweet. I like them somewhere in the middle. For me, grapes, oranges, raisins and bananas are sweet. What's the most bitter fruit you've ever eaten? What's the most sweet fruit?
