This a Moonmelon, scientifically knows as asidus. This fruit grows in some parts of Japan, and is known for its vibrant blue color. What you probably don’t know about this fruit is that it can switch flavors after you eat it. Everything sour will taste sweet, everything salty will taste bitter, and it gives water a strong orange-like taste. It's also very expensive...costing about ￥16000 JPY (which is about 200 dollars).
The ‘Indigo Rose’ is a new, strangely-colored variety of tomato. The fruit is jet black on the outside and juicy purple-red on the inside. These colors might not sound very appealing, but black tomatoes are supposed to be very tasty, and most importantly, rich in antioxidants. Indigo Rose is a cross-breed between red and purple tomatoes, and is the latest ‘superfood’ to hit the market.
