Tamarillos are revered for their beauty as well as their juicy, moist flesh. Shaped like a pointed egg, tamarillos come in clusters of three or more and each fruit is about two inches long. Similar in taste to a plum or an apricot, the fruit is perfect for cooking. A good source of vitamins A and C, tamarillos are low in calories. They are known as “tree tomatoes” and come in both red and gold varieties. Once ripened at room temperature, refrigerate for up to 10 days, tightly wrapped in plastic.
