1. Prepare all the ingredients for the cake.
2. Add the food coloring to the milk and mix well.
3. Separate the egg white and egg yolk, add corn oil to the egg yolk and stir well.
4. Add milk coloring and mix well with a manual whisk.
5. Sift low-gluten flour into the stirred milk paste (the main function of sieving is to remove the agglomerations produced during the storage of the flour and make the flour more fluffy).
6. Use a manual whisk to stir until the flour is not granular. If there are bubbles in the batter, just lift the basin and shake it gently, and the bubbles will disappear naturally. Put the mixed cake batter aside for later use.
7. Put the separated egg whites in the egg-beating bowl, add white sugar, and beat them at high speed into a fish-eye bubble state, and then add 1/3 of the fine sugar. Whisk with an electric whisk until the volume has doubled, and then add 1/3 fine sugar. Just hit it to a wet foaming state. A small hook (as shown in the figure below) can be pulled out from the whisk, which is a wet foam.
8. Take 1/3 of the meringue and put it in the egg yolk paste. Use a spatula to draw a zigzag and quickly stir evenly. The process should be light and fast.
9. Then pour all the mixed batter into the remaining meringue, draw a zigzag with a spatula and quickly stir evenly.
10. Pour all the cake batter slowly from 30cm into the mold, shake it gently twice to eliminate the big bubbles in the batter. The preheated oven is heated at 170°C up and down, in the middle level, and bake for about 20 minutes. The baked cake rolls are immediately out of the oven to let cool.
11. Put the whipped cream in an egg beater and add powdered sugar.
12. Use an electric whisk to whip the cream, as shown in the picture.
13. Put the cold cake roll on a piece of greased paper, smear the whipped cream, place the strawberries, and then apply a house of cream to wrap the strawberries.
14. Using a rolling pin as an aid, roll up the cake and put it in the refrigerator for 30 minutes before serving.
Tips:1. The amount of whipped cream can be adjusted according to your liking.
2. If there is red velvet liquid, there is no need for pigment.
