This recipe allows you to easily recreate the hugely popular Korean "Kam Japan" (potato bread) at home. A smooth, gently sweet filling is made by mixing microwave-heated potatoes with vanilla ice cream, and then wrapped in a chewy dough made with rice flour and potato starch. It's finished off by dusting it with kinako (roasted soybean flour) and black sesame seeds to resemble a potato, and then steaming it. The chewy texture and the simple sweetness of the potato are addictive, making this an easy-to-make and trendy dessert.
