When I was a child, the fried sweet potato buns on the street were sweet and crunchy, and I had a happy day. I can't find it now, give it a try.
Cut the sweet potato into small squares, put in the pot and add the eggs, flour, water starch and stir evenly (the water can be put less, or the sweet potato will be scattered) can also put less sugar.
Use a spoon to spread the prepared sweet potato diced on the colander, and try not to sew it in the middle.
Heat the oil to 70% heat, put the sweet potato on the colander into it, fry for about two minutes, tune in the fire, fry the sweet potato cake, use the chopsticks to slowly clip the sweet potato cake from the colander, continue to fry until Golden fried.
Can be tied with chopsticks to soften.
Eat hot, soft and sweet.
