Tamarillo

Tamarillo is a small, egg-shaped fruit grown on an evergreen tree native to the Andes Mountains, now produced commercially in New Zealand, Australia, South Africa, and parts of South America. Despite its common name "tree tomato," it belongs to a distinct species within the Solanaceae family and should not be confused with true tomatoes (Solanum lycopersicum). The fruit has smooth, waxy skin—typically deep red or golden-orange depending on variety—and soft, edible seeds embedded in flesh that ranges from burgundy to amber. Its flavor is its defining feature: bright, tangy acidity with only mild sweetness, making it far more assertive than a standard tomato. This tartness is what makes tamarillo so useful in the kitchen, lending itself equally to sharp chutneys and sweetened breakfast preparations. The name "tamarillo" was coined in New Zealand during the 1960s for marketing purposes; in Spanish-speaking regions it is called tomate de árbol, while in Colombia it may be referred to as tamamillo.

Behaviorally, tamarillo differs from true tomatoes in important ways. Its flesh is less juicy and more dense, and its acidity registers at pH 3.0–4.0—significantly lower than most common tomatoes. The skin, while thin, carries a noticeable bitterness that most cooks remove before using. Raw tamarillo has a texture somewhere between a firm kiwi and an underripe tomato, with a pleasant tartness that wakes up the palate. When cooked, the flesh softens readily and breaks down into a smooth, intensely flavored pulp. Tamarillo also contains notably high levels of vitamins A, C, and E, along with potassium and iron, making it not just versatile but genuinely nutritious.

Seasonality shapes tamarillo quality more sharply than with common tomatoes. In the Southern Hemisphere, peak season runs March through August; in the Northern Hemisphere, look for the best fruit from September through February. Outside these windows, tamarillos available in standard supermarkets are often mealy and insipid. When selecting, choose firm fruit that gives slightly under pressure; avoid any with wrinkles or soft spots, which indicate age. Once ripe, refrigerate and use within one to two weeks, or freeze the pulp for up to three months.
