One of my favorite sweets is “SWEET POTATO”.
Although “sweet potato” is a name of a kind of potatoes in English, “SWEET POTATO” is a name of sweets in Japan – we call sweet potato “SATSUMAIMO(サツマイモ)”.
As you infer from the name, SWEET POTATO is made of sweet potato.
Sweet potato is boiled and strained. Next, sugar, milk, butter and spice like vanilla are added. After shaping potato’s dough into a oval, egg yolk is spread on it. Finally it is baked.
It is very delicious.
