Banh khoai (delicious pancake) is so much like Banh xeo (sizzling pancake) since they both are made from rice flour, water, turmeric powder, added slivers of fatty pork, shrimp, bean sprouts and then pan fried. Banh khoai and Banh xeo also are wrapped in mustard leaf, lettuce leaves or rice paper, and stuffed with variety of herb, like mint leaves, basil and served with a sweet and sour mixed sauce. In Hue, Banh khoai is placed open-face instead of being folded in half like Banh xeo. Moreover, Banh khoai always goes with a fermented soy bean sauce, and people consider it a winter food owing to its greasiness and spicy taste of the sauce. Therefore, most Hue citizens only make them when winter coming.
