Pitaia, or Dragon Fruit (also known as ‘strawberry pear’), is native to tropical regions and actually comes from a cactus. Taste-wise, it’s not too sweet but due to the tiny black seeds, it looks a bit (on the inside) and tastes a bit like a kiwi.
The red flesh version shown in the first picture above is called a Costa Rican Pitaya in English. Other versions include the Red Pitaya which has red skin and white flesh while the Yellow Pitaya has yellow skin and white flesh. All three are quite high in vitamins and minerals.
