Oleh hiropon08020 , This is one of the traditional Japanese sweets, especially in Kyushu area. Basically, the word "Ikinari" means "suddenly" in standard Japanese, while it has some other meanings in Kyushu dialects like "directly" or "roughly." So, there are a number of stories about the title... For example, it is named "ikinari" because we can make it in a short time by using uncooked sweet potatoes directly (=ikinari), or we can make it roughly, without any special cautions (=ikinari). I'm not sure which story is true, but believe me, it's so nice for sure!
