Sweet Potato Cake Roll
1.
Separate the egg yolk from the egg whites in two clean, dry bowls. First, beat the egg yolks, add sugar to the yolks, and beat them with a whisk.
2.
The yolks are beaten until they are thick and lighter in color.
3.
Then add salad oil (corn oil or other odorless vegetable oil) in 3 portions. Each time you add it, use a whisk until it is mixed, then add it a second and third time.
4.
Then pour the milk and stir gently.
5.
Finally, sift in low flour and baking powder, and stir up and down with a rubber spatula to form a delicate egg yolk batter.
6.
Stir the egg yolk paste, set aside and set aside.
7.
Then the whisk should be cleaned and wiped dry. Whip the egg whites and sugar, pour them into the egg whites three times, and use a whisk to beat each time you pour some. From the very beginning, the fish eyes become thicker and thicker.
8.
About 2 minutes, 80% of the egg whites are beaten. After lifting the whisk, you can pull out the curved sharp corners.
9.
Pour the whipped egg whites into the egg yolk batter 3 times and mix evenly.
10.
The third addition can be the other way around. Pour the batter into the last remaining egg white bowl, and then mix it up and down evenly. (You don't need this method, just mix it evenly by yourself)
11.
Finally, pour the stirred flour into a baking pan lined with tin foil (oil paper). (At this time, the oven can be preheated, the temperature of my home is too high, preheat at 160 degrees for 5 minutes)
12.
Pour evenly and shake off some bubbles. Put it in the oven, 160 degrees, bake for 20 minutes
13.
When baking cakes, make sweet potato sauce. First peel and slice the sweet potatoes, steam them, put them in a food processor, add milk and condensed milk (a little bit of milk is almost enough)

Stirred Sweet Potato Sauce
15.
Prepare a piece of greased paper or tin foil, spread it out, buckle the baked cake upside down on the greased paper, peel off the tin foil from the cake while it is hot, and the cake floor faces up. Let cool for a while and spread the mashed sweet potatoes evenly (forgot to take pictures)
16.
Roll from bottom to top, put in the refrigerator for half an hour, then cut into pieces and enjoy.
17.
It's done!

Do you think it's pretty good?
