Often when we see a new fruit we will ask the vendor what it tastes like. It is funny because the person you are talking to will inevitably have a different answer than the people sitting around them. It seems the vendor will say the fruit is sweet. Her companions will laugh and say that really it is sour. Somewhere along the way it gets decided that the fruit is sweet and sour. I don't know why we still ask; it just seems to be the thing to do. At least then if we find our eyes watering and mouth doing the funny little contortions that follow eating something unexpectedly sour, we can say that we asked.
I suppose that could be part of the fun on their side too. Perhaps they want to convince us the new fruit is sweet and that we should try some. Then when we do the puckered, cross-eyed thing they can have a new cultural experience - they may have never seen an Americano do that before. Or maybe they have and that is why the response is so consistent...
Well anyway, this fruit was sweet; no crossed, watery eyes or puckered cheeks. Of all things, it reminded me somewhat of saltwater taffy.
Let us know if you have any guesses.
