Very Harbin Lilac Blossoms Fantasy Lilac Cake Roll

Pour milk and corn oil into a basin and stir until emulsified evenly.

Sift in the low-gluten flour and stir evenly using a 'Z' shape.

Pour in the egg yolk and stir evenly.

Add appropriate amounts of white pigment and purple pigment to achieve the desired color. Be gentle in this step. If the color is too light, you can adjust it later. The color will become darker after baking.

Add lemon juice to the egg whites that have been frozen until they are frozen on the edges. Add sugar in three batches and beat until they become slightly curved.

Put about one-third of the beaten egg whites into the egg yolk paste and mix evenly.

Pour the evenly mixed egg yolk paste into the meringue basin and mix evenly.

Pour the mixed cake batter into the baking pan from a height of about 15 cm. Shake it left and right to spread the cake batter evenly on the baking pan. Use a scraper to smooth the surface and shake it gently to release large bubbles.

Put it into the oven for baking, with the upper and lower tubes set to 150 degrees, and bake for about 35 minutes.

After baking, remove from the baking pan and place on a drying net to cool. When there is no heat, cover with oil paper to prevent drying.

Cut off one side of the cake slice at an angle of about 45 degrees.

Add sugar to the whipped cream and beat until it is about 90% stiff.

Put the whipped cream into a piping bag, squeeze it onto the cake slice, and smooth it out.

Use a rolling pin to help roll it up and put it in the refrigerator to refrigerate.

Soften the cream cheese, add sugar, and mix with a spatula until smooth.

Add a little room temperature light cream, mix with a spatula until smooth, and adjust to a softness and hardness similar to salad dressing. Add a little purple pigment to adjust the color.

Install a piping bag and pipe spiral lines in circles starting from the center of the plate.

Place a small spatula in the middle of the plate, place the plate on the decorating table, and turn it to spread it out.
