After a day, I didn't burn my hands and tried not to eat them all because it was cold
I'm going to use the sweet potatoes left after this
I'm going to make mattang.

If you make it with raw sweet potatoes
You have to cut the sweet potatoes and fry them.
If you use boiled sweet potatoes, you can skip the frying process
It's easier to make it faster.

First, cut the remaining boiled sweet potatoes into bite-size pieces.
The frying process is omitted
It's easier to make sweet potato glazed sweet potato

Put some oil on the sliced sweet potatoes
Please stir-fry it.
Then you can prevent it from breaking.
And oligosaccharide
Please add a little bit of soy sauce.

Next, it's boiled sweet potato so that it doesn't break
Stir-fry the ingredients gently.
And lastly, sprinkle black sesame.
Then, I'm done

Let's see the transformation of a newly boiled sweet potato
It's reborn as mattang.
It hardens little by little as it cools down with oligosaccharide
You can taste mattang with good texture.
