Filipino Purple Yams, Ube, promptly show up at the local Asian market during season every year. They have a gorgeous purple flesh and a delicately sweet taste, primarily used in desserts.
Since I am not fond of desserts much, I went with a simple oven-roasted purple yam fries. Tossed in coconut oil with a dash of salt, single layer in a roasting pan, in a 425°F oven for about 15 to 20 minutes. That's it. A perfect Autumn snack ready in no time.
