Guanabana ( Spanish for soursop) is a tree native to the Caribbean and some parts of Central and South America.
While in Costa Rica we could not go past the fruit in the supermarket as it was of a size of an American football ball. We decided to give it a try.
The flavor of guanabana is probably closest to a pine-apple with a combination of citrus and somewhat creamy flavors. While dark green on the outside, the white interior is full of big dark seeds. The fruit is quite juicy so were a bit messy.
We were told by locals that when you buy this fruit you should touch it and feel some sort of softness of the skin and it means that the fruit is ready to be consumed. The locals often blend a guanabana pulp with some milk and have it as a drink instead of eating it.
