Cooking Steps

1. 

   Step1:Separate the yolk from the protein. The bowl of protein needs no oil or water. Mix the yolk with the sugar and beat well with the beater. Add salad oil (or sunflower seed oil and other odorless vegetable oil) three times. Beat each time you add it with an egg beater until it is well mixed and then add another time. Add water (or milk). Stir gently.

2. 

   Step2:Cocoa powder and low gluten flour are sifted into the yolk. Mix well with a rubber scraper to make egg yolk batter. Put the batter aside and set aside.

3. 

   Step3:Start to kill the protein. Add sugar at one time. Low speed first, then high speed. Send the protein to the state of wet foaming (after lifting the eggbeater, the protein pulls out the curved sharp corner

4. 

   Step4:Put 1 / 3 protein into the yolk bowl. Stir evenly (from the bottom up. Do not circle). Add 1 / 3 protein to the yolk bowl. Stir well. Pour the batter into the remaining protein. Mix well again.

5. 

   Step5:Pour the batter into the baking tray paved with tin paper or oil paper, level it, and shake it hard for a few times to let the big bubbles inside the batter run out. Place the pan in a preheated 180 degree oven. Bake for 15 minutes.

   Step6:Whipped cream 100g. Sugar 10g. Beat with electric beater until stiff.

7. 

   Step7:Prepare a new piece of tin paper or oilpaper. Pour the cake on it. Tear off the tin paper or oilpaper on the cake while it is hot. The bottom of the cake is facing up. When the cake has cooled down a little, turn it over and make it face up again.

8. 

   Step8:Spread a layer of whipped cream over the top of the cake. Leave no or less cream on the last edge.

9. 

   Step9:On the side to be rolled up, first pull a knife with a knife, but do not cut it. This is more convenient when rolling. Roll from the end of the cut. Roll all the way to the back. Cut off the back edge. It looks neat. Finally, wrap the rolled cake with tin paper or oil paper. Twist both ends into candy shape. Refrigerate for half an hour.

10. 

    Step10:Half an hour later, take the cake roll out of the refrigerator. Spread a layer of cream on the outside. Sprinkle with black chocolate chips (the chocolate softens in advance. Use a small spoon to scrape into chocolate chips). Squeeze three pieces of cream on it. Garnish with three strawberries.
