Tomate de Arbol
Native to the Andean region, Tomate de Arbol (Tamarillo) is a fruit that is often used to make juice in Colombia. The juice has a bitter sweet, kind of acidic taste. However, don't be confused by the name, it tastes nothing like a tomato. It is most common in the Eje Cafetero and el Valle.
The trees that grow the fruit are usually found between 1500-2500 meters above sea level, in temperatures between 15 and 22 degrees celsius. The fruit itself is high in fiber, and vitamins A, B, C, and K. It is also rich in calcium, iron and phosporus.
Make sure to give it a whirl while in Colombia.
