Tropical Fruit - Part 1

(Two different kinds of bananas that grow on our neighbor's trees... both are delicious)

There is an orchard on this property, full of tropical fruit trees. There are at least 7 different varieties that I can see, if you count the pineapple plants, and banana trees down the road, but most of the fruit are a complete mystery to me. 

When i first learned about the orchard I imagined sipping fresh mango smoothies or piña coladas while watching the sunset.  Instead,  we found these beasts: 

(What... the heck? Is that?)

I did some research at the grocery store and found drink mix with pictures of the same fruit, along with the name: guanabana. 

(Cool-aid proves to be useful for the first time ever.)  

One You Tube video later I was ready to prepare and eat my first guanabana.  

But it turns out I picked this guy a little too early (maybe a lot early).  It was not ripe at all, the flesh was  hard and tasteless, and I ended up tossing it out. 

Apparently the outside should be slightly yellow when ripe.  Thankfully there's still another one on the tree.  Lesson #342 of living in Costa Rica learned: wait for the fruit to ripen before you harvest. Check.
