Understanding Taro and Ube (The Real 'Purple Taro')
The phrase "purple taro" is a common misnomer that actually refers to ube, or purple yam. True taro root, scientifically Colocasia esculenta, is a versatile corm native to Southeast Asia, while ube, Dioscorea alata, is a species of yam originating from the Philippines. This fundamental botanical difference leads to significant variations in appearance, flavor, and culinary applications.
The Characteristics of True Taro
True taro root has a rough, brown, and fibrous outer skin. When cooked, its starchy flesh typically reveals a pale white color with subtle, delicate purple speckles. Its flavor profile is often described as nutty and earthy, with a mild sweetness reminiscent of a plain potato or a chestnut. The texture of cooked taro is denser and more fibrous than ube, making it hold its shape well in dishes.
Culinary uses for taro are incredibly diverse, spanning both savory and sweet applications. In savory dishes, it can be roasted, boiled, or used in stews and soups, absorbing the flavors of other ingredients. For sweet preparations, like the famous taro milk tea, it provides a subtle, nutty, and creamy foundation.
The Profile of Ube (Purple Yam)
Ube, the vibrant purple yam, is what people often have in mind when they say "purple taro." Native to the Philippines, this tuber is known for its stunning, deep purple color, which intensifies when cooked. The color comes from anthocyanins, powerful antioxidants. Ube is naturally sweeter than taro, with a distinct flavor profile that includes notes of vanilla, pistachio, and white chocolate. Its texture is creamier and less fibrous than taro, making it perfect for smooth, sweet preparations.
Ube is almost exclusively used in desserts. It is the star ingredient in Filipino delicacies like ube halaya (a sweet jam), as well as cakes, ice creams, and pastries. The vivid purple hue makes ube-infused foods visually striking and a social media favorite.

How to Tell Them Apart
When at the market, you can distinguish taro from ube by a few simple observations:
- Exterior: Taro typically has a rough, brown, and somewhat hairy outer skin, while ube's skin can vary but is often darker and smoother.
- Interior (Raw): If you can see a cross-section, taro will be white or pale lavender with characteristic purple specks. Ube will have a solid, deep purple interior.
- Intended Use: The vendors or labels may indicate the intended use. "Purple yam" or "ube" will be marketed for desserts, while taro is sold for more general cooking.
The Importance of Proper Cooking
Both taro and ube are toxic if eaten raw due to calcium oxalate crystals. They must be cooked thoroughly through boiling, steaming, or baking to neutralize these compounds and render them safe for consumption. Proper handling with gloves is also recommended during preparation to prevent skin irritation.
Why the Misconception?
The confusion between taro and ube largely stems from their shared use in popular drinks and desserts, particularly bubble tea. Some establishments use artificial taro flavoring or powders that mimic the vibrant purple color of ube but lack the authentic earthy flavor of real taro. The visual similarity in the finished product perpetuates the idea that they are the same plant. Furthermore, both are starchy tubers from tropical regions, leading to them being grouped together by casual consumers.
Conclusion
The key to understanding the difference between taro and purple taro lies in recognizing that "purple taro" is not a distinct taro variety but rather a different vegetable altogether: ube, the purple yam. Taro offers a subtle, nutty flavor ideal for a wide range of savory and sweet dishes, while ube provides a sweeter, vanilla-like profile and a more intense purple hue, making it perfect for vibrant desserts. By knowing the distinctions in flavor, color, and texture, you can confidently choose the right ingredient for your next culinary adventure.

What is the difference between taro and purple taro?
Appearance and Color: Ube (purple taro) is a purple yam with a consistently vibrant, deep purple flesh, while true taro has a paler, often white or light lavender flesh with distinct purple flecks. Taro's color is less saturated and can appear grayish when cooked, whereas ube maintains a brilliant purple hue.
Flavor Profile: Ube is significantly sweeter with rich notes of vanilla and pistachio, making it a dessert ingredient. Taro has an earthier, nutty flavor with a milder sweetness, making it suitable for both savory and sweet recipes.
Texture Differences: Ube's texture is creamy and soft, almost like a sweet potato, which is ideal for smooth purées and fillings. Taro has a denser, starchy, and slightly fibrous texture that holds up well in soups and other cooked dishes.
Culinary Uses: Ube is almost exclusively used in sweet applications, such as ube halaya, ice cream, and cakes. Taro is more versatile and can be used in savory stews and curries, as well as desserts and beverages like taro milk tea.
Geographical Origin: Ube is native to the Philippines, while taro has a broader origin spanning Southeast Asia and India, and has been cultivated in many tropical regions, including Hawaii.
Nutritional Content: While both are nutrient-dense tubers, taro is known for being exceptionally high in dietary fiber. Ube's vibrant color comes from anthocyanins, powerful antioxidants that contribute to its health benefits.
Common Misconception: The main reason for the confusion is that many commercially available taro-flavored products, like bubble tea powders, use ube or artificial coloring to achieve a bright purple color, masking the true difference.
