This dish shares a lot of similarities with bot chien. They're both popular with school kids (usually as an afternoon snack), they both consist of fried up cubes of deliciousness with egg, green onions, and oil, and they're both heavy but satisfying. Their differences are mainly that bot chien is made with rice flour, while bột khoai môn is made with taro flour (and usually some rice flour as well). Personally, I find banh bot khoai mon a bit tastier. It has a nice potato taste to it and reminds me of a breakfast hangover concoction that you might have found at my house when I was in college.
