There are two types of purple yam:
- The Filipino "ube" or "ubi" (not usually available in the US), which has darker, rougher-looking skin. It grows on a vine above the ground, so is quite different from regular yams. This vegetable is a major crop and food source in the Philippines. It is also made into a powder which is then used in Filipino desserts (you'll know them by their bright purple color!).
- The Purple Okinawan Sweet Potato (pictured here) is ground underground and is similar to Western sweet potatoes and yams. From the outside the purple yam / sweet potato looks the same, but cut one open and you'll know the difference! These yams are wonderful boiled, steamed, or baked alongside regular yams and sweet potatoes.
Purple Yam Nutrition:
Like regular yams, purple yams are extremely good for you. High in potassium, plus B6, vitamin C, fiber, plus antioxidants, purple yams are truly one of nature's wonders.
