  8. Add lemon juice to the egg whites and beat until thick.(If you don’t have lemon juice, you can use white vinegar instead, or you can leave it out)

• 

  9.Add sugar in one go (You can also add it in three times.I like to add it all at once and then beat at low speed.) Beat at low speed until all the sugar has melted, then beat at high speed (this process is very fast, about a minute or two)

• 

  10. Beat until there is a long hook when you lift the egg beater

• 

  11.Put half of the egg whites into the egg yolk paste and mix evenly (remember not to stir in circles)

• 

  12. Pour all the mixed egg yolk paste into the egg whites, and mix evenly using the same technique

• 

  13. Stir evenly until the texture is smooth and even in color

• 

  14. Cover the baking pan with oil-absorbing paper in advance, and pour the mixed cake batter into the baking pan (at this time, the upper and lower tubes of the oven are preheated to 170°C)

• 

  15.Scrape it flat with a spatula and gently shake out the bubbles

• 16. Place in the middle rack of the oven and bake at 170°C for 20 minutes (the oven temperature and time are for reference only)

• 

  17.Take it out quickly after baking

• 

  18. Cover with oil-absorbing paper and flip it over with the help of the baking mesh (you can also directly attach it to the baking mesh without wasting the oil-absorbing paper)

• 

  19. Gently lift off the oil paper after folding it.If you want to apply jam or cream, turn it over and apply it on the front.It is best to let it cool down before applying it

• 

  20. Roll it up with oil-absorbing paper and put it in the refrigerator for about an hour to set
