I can cook meals, but not sweets!

It's steamed glutinous rice (I just cook this normally in a rice cooker) mixed with sugar, roughly mashed, then mixed with soft-boiled sweet potatoes and mashed further, and finally coated with a generous amount of kinako (roasted soybean flour). Apparently, it's called 'Neibo' in my mother's hometown (the same place as that guy from 'Dogeza de Tanondemita' and the beloved Jirou Okamoto), and in Kagoshima, they call it 'Nettabo'. I'm making both plain and red bean paste filled versions. You know how they say 'making sweets is science, cooking is addition'? I just can't measure things... I'm all about eyeballing it... This 'Neibo' is barely addition, so it's one of the few sweets I can actually make.
