Beat the eggs properly. To do this, break them into a clean, dry bowl and add sugar. Beat with a mixer or whisk until white for 7 minutes.
Add soda, quenched in vinegar, to the resulting mixture.
Add the remaining ingredients to the resulting mixture and mix with a mixer until smooth.
Start baking. Pour the dough into the prepared form and put it in the preheated oven. Take it out after 25 minutes and wait until the sponge cake cools down. As you can see, the recipe is very simple.
