Video Double Blueberry Cake
1.
[Sponge cake (divided egg)]: Mix butter and milk, heat it over a small fire or over water until it melts, and set aside.
2.
Separate the egg white and egg yolk, and beat the egg white (the appliance that touches the egg white needs to be water-free and oil-free). When making big bubbles, add 1/3 powdered sugar, when the bubbles become fine and small, add 1/3 powdered sugar, when the lines begin to appear, pour in the remaining powdered sugar, and finally 90% of it will be beaten. Lift the beater head and it will hang down. Sharp corners. Add egg yolks and continue to beat at medium-high speed for about 2 minutes.
3.
The final dismissal state: lift the egg beater and draw an "8", and the egg paste can be kept for more than 10 seconds. (Or take a toothpick, insert the batter 1cm deep, the toothpick will not fall, it means that the batter is in place.)
4.
Sift 1/2 low-gluten flour into the beaten eggs and stir until there is no dry powder; then sift in the remaining low-gluten flour, and stir until there is no dry powder. Do not over-mix to avoid defoaming. (Don't stir in circles)
5.
Add two spoons of batter to the milk and butter solution and mix well.
6.
Pour the butter and milk solution back into the batter, and stir evenly.
7.
Cover the 7-inch and 4-inch molds with baking paper in advance, pour the batter from a height of 10 cm, and knock twice to shake out bubbles. Put it in a preheated oven at 160 degrees, and bake for about 40 minutes.
8.
Knock on the table after coming out of the oven to shake out the heat, so that the cake will not easily retract, and the cake will be demoulded after it cools down. (Sponge cake is not as easy to retract as chiffon. It takes about 5 minutes to invert, and the problem of cooling without inversion is not big.)
9.
Cut the 4-inch and 7-inch cakes into 2 layers, and brush the cut surface with a layer of sugar and wine to make the cake more moist.
10.
[Blueberry sauce]: Use a food processor to beat the puree of blueberries, pour into a small pot, add sugar, and cook for 5-7 minutes on low heat to make the jam thick. After cooling, put it into a piping bag for later use.
11.
[Cream]: Add icing sugar to the whipped cream, whipped 80% to 90% (it is not easy to wipe the noodles if completely whipped), 1/3 of the whipped cream, put it into a piping bag.
12.
Take a 7-inch cake base, squeeze a layer of cream, squeeze another layer of blueberry sauce on the cream, and cover with another layer of cake base.
13.
Add an appropriate amount of blueberry sauce to the remaining 2/3 of the cream and mix well.
14.
Use blueberry cream to spread the surface of the cake (see the video for the specific method). The same applies to the 4-inch cake.
15.
In the middle of the 7-inch cake, in the equilateral triangle position, insert 3 straws of the same height as the cake, so that there are straws to support, when the second layer is placed, the cake will stand upright.
16.
Using two spatulas, transfer the 4-inch cake to the 7-inch cake.
17.
Decorate with blueberries and mint leaves.
18.
When cutting the cake, use a sharper knife.
