What is Purple Yam (Ube)?
Purple yam, or ube (pronounced “ooh-beh”), is a tuberous root vegetable native to the Philippines that has recently skyrocketed in popularity. Its name means “tuber” in Tagalog, and for generations, it has been a staple in Southeast Asian cooking. While it might look unassuming from its rough, grayish-brown exterior, slicing into it reveals a truly stunning, deep violet flesh. It's this beautiful color, combined with a uniquely delicate flavor, that makes ube so beloved in countless desserts, pastries, and beverages worldwide.
The Flavor Profile of Purple Yam
If you're asking, "what does a purple yam taste like?" you can expect a complex, yet subtle, combination of flavors that are less intense than its more common cousins, like the sweet potato. Ube's flavor is often described as:
- Sweet with vanilla notes: Ube has a natural, mild sweetness that is often compared to white chocolate or creamy vanilla. This inherent sweetness is what makes it so suitable for a variety of sweet treats, from ice cream to cheesecake.
- Slightly nutty: The flavor also carries a distinct nutty undertone, with hints of pistachio or even coconut. This provides a rich, earthy depth that prevents it from being one-dimensionally sweet.
- Earthy and mellow: While it has a nutty profile, ube also retains a pleasant earthy quality, characteristic of a root vegetable, but without being overpowering. Its mellow nature allows it to absorb and complement other ingredients beautifully, such as condensed milk and coconut milk.
Ube's Unique Texture
Beyond its flavor, ube's texture is a key component of its appeal. Unlike the dry, starchy texture of some sweet potatoes, cooked ube becomes soft, moist, and slightly sticky. When pureed, it can achieve a velvety, silky smooth consistency, which is perfect for traditional Filipino jams like ube halaya. This smooth texture is why it is so highly sought after for creamy desserts like ice cream, custard, and fillings.
Purple Yam vs. Other Purple-Hued Tubers
It is common to confuse ube with other purple-colored root vegetables, most notably purple sweet potatoes and taro. However, their flavors and textures are quite distinct. Understanding these differences is crucial for any cooking enthusiast.

How to Use Ube in the Kitchen
Because of its versatility, ube can be incorporated into a wide range of sweet and savory dishes. Its mild, sweet flavor allows it to be used in desserts, while its earthy undertones make it suitable for balancing savory dishes.
Classic Filipino Ube Dishes
- Ube Halaya: A traditional Filipino sweet jam made from boiled and mashed ube mixed with condensed milk and coconut milk. It is rich, creamy, and can be enjoyed on its own, spread on toast, or used as a filling.
- Halo-Halo: A popular Filipino shaved ice dessert that features ube ice cream or ube halaya as a key topping, along with other ingredients like fruit, leche flan, and condensed milk.
Modern Ube Creations
- Baked Goods: Ube has become a trendy flavor for pastries, such as ube crinkle cookies, cupcakes, and croissants.
- Beverages: Ube lattes, milk teas, and smoothies are now a common sight in cafes, valued for both their flavor and vibrant purple color.
- Savory Applications: In some Filipino dishes, ube is used in stews or mashed as a vibrant side dish, where its mild sweetness complements other savory flavors.
How to Experience the Real Ube Flavor
To truly understand what a purple yam tastes like, it's best to start with a product made from real ube. The flavor of natural ube is more delicate than artificial flavorings. Here’s how you can find and use it:
- Fresh or Frozen: Look for whole or grated ube at Filipino or Asian grocery stores. It is often sold frozen outside of Southeast Asia. Be sure to cook it thoroughly, as it contains some toxins when raw.
- Ube Extract: The most accessible option for home cooks, ube extract provides the distinct vanilla-nut flavor without altering texture. It's a great way to introduce the flavor and color into baked goods and drinks. For some great recipes using ube extract, visit King Arthur Baking.
- Ube Powder: This is a dehydrated form of the yam that can be rehydrated and used in recipes like fresh ube, and it retains much of the original flavor.

Its complex flavor profile—a harmonious blend of nutty, earthy, and vanilla-like sweetness—offers a unique culinary experience.
