|Metallic Spheres of Wondrous Warmth|
|the answer: sweet potato|
When the need for heat expires, you aren't stuck with a blob of foil, you're rewarded with a savory morsel of orange-colored food! While in America many grow accustomed to greasy sweet potato fries and baked incarnations attacked by butter, on a winter's day a plain and simple sweet potato is a welcome festival in your mouth!
If you happen to be traveling in 青森市/Aomori City, be sure to make a stop at the green colored stand in front of the 青森駅/train station and for￥200 ($2.41) treat yourself to an edible hand warmer.
PS: Special thanks to Jaewon Yoo for introducing me to this warm and tasty concept!
