The subtle saltiness is really delicious.
I love the sweet potato variety that's grown in our region, Naruto Kintoki. I adapted the salt-less recipe my older sister has been making for years to make a trendy salty version.
Please adjust the microwave time depending on your oven. We have a gas oven, which gets rather hot.I recommend using a good quality and tasty salt.
Enjoy Japanese food around the world.
