A red, egg-shaped tropical fruit about the size of a plum. It is sometimes called a tree tomato. It is usually eaten cooked and can be quite tart when raw, though a sprinkling of sugar can help. Avoid eating the skin, which is bitter, but use the flesh in ice creams or sorbets and serve cooked tamarillo with poultry or fish. You can also use tamarillos in the same way as tomatoes to make sauces or chutney.
