Oranges in Spanish are called naranjas.  As you can see, Costa Rican oranges look very different from ones you find in the United States.  The outside is greenish brown and the color varies throughout the peel.  In contrast to the perfectly orange color, these found in Costa Rica are not very attractive.

However when you slice this fruit in half, it looks just like an orange I would find back home.

The membranes that hold the fruit together tend to be quite tougher than American oranges.  I find that these fruits are best used for juicing.  About 4 oranges make 16 oz of juice, and its very refreshing and satisfying!  We had some for breakfast yesterday morning and its much better than the store bought juice which, for reasons that are beyond my comprehension, contains added sugar.

It takes a bit more work to make my own juice, but the effort is well worth it!
