I was at the local supermarket and noticed a young man picking up 4 of these alien looking fruits, so I accosted him (I don't make a habit of addressing strange men in the grocery store but he didn't mind) and asked what they were and what he was going to do with them.
He told me Dragon Fruit...... these were imported from Vietnam according to the label. Just slice in half and scoop the innards out with a spoon. So of course, I had to buy one, just to experience the taste.
It's supposed to taste like a combination of pear, kiwi and watermelon. I'll let you know.
