Cherimoya
It looks like a heart-shaped artichoke but the cherimoya tastes sweet and creamy, like a cross between banana and pineapple.
It is delicious eaten fresh as is but you can also use it in juices, smoothies and fruit salads. Called the "ice cream fruit," many people chill it and eat with a spoon. You can also remove the seeds, freeze for 4 to 5 hours then blend to make a creamy cherimoya sorbet.
A cherimoya will give you over 10 percent of your daily recommendations for fiber, vitamin C, potassium, vitamin B6 and riboflavin. You can find this fruit at specialty markets.
