Then, I cut it open.
Nope, not a kiwi. With reddish-orange flesh and a few shiny, black, almond-shaped seeds, this probably isn't even closely related to a kiwi. I grabbed a spoon and scooped out a sample (just like a kiwi). It was good! Sweet and soft, it reminded me of a ripe pear.
A few days later, I found some at the Cold Storage grocery store where, like American stores, they had a big sign with the fruit's name and price. The mystery fruit is called a Ciku (pronounced "CHEEK-oo"). It's also know as a zapota, sapodilla, chico, and chicozapote. It turns out that my mom had been asking me during our Skype calls if I had tried a ciku. Now, I can say, "Yes."
