Chocolate sponge cake on proteins

Step-by-step cooking

1. Step 1:

   

   Sponge cake ingredients.

2. Step 2:

   

   Whisk the proteins, we start whipping at the lowest speed of the mixer and as the proteins increase in volume, we increase the speed. Whisk the proteins to a density, add sugar (50 g) and lemon juice, whisk until a dense shiny mass.

3. Step 3:

   

   Add vanilla tincture and mix.

4. Step 4:

   

   Sift flour with cocoa and powdered sugar, add to the whipped whites.

5. Step 5:

   

   Mix gently, do it quickly so that the proteins lose as little air as possible.

6. Step 6:

   

   We put the dough into the mold, the mold does not need to be lubricated with anything!

7. Step 7:

   

   Bake in a preheated 180 C oven for about 25-30 minutes, do not open the oven for the first 20 minutes. We check the readiness with a skewer.

8. Step 8:

   

   We take the biscuit out of the oven and leave the top to cool upside down (that's why we don't lubricate the shape, so that the biscuit just doesn't fall off it during cooling). It is customary to cool such biscuits upside down, for the reason that even under its own weight it can settle.

10. Step 9:

    

    While the sponge cake is cooling, prepare the glaze.

11. Step 10:

    

    Add sugar to the water, send it to the fire, bring the syrup to a boil and cook for 2-3 minutes on medium heat, the sugar should completely dissolve.

12. Step 11:

    

    Let the syrup cool for a few minutes and add cocoa powder and vanilla, mix, you can even beat a little with a mixer until smooth.

13. Step 12:

    

    The cooled biscuit is released from the mold, for this you need to hold a knife along the mold.

14. Step 13:

    

    We cover the biscuit with glaze (if you want the glaze to completely cover both the top and sides, the amount of glaze needs to be increased), decorate as desired.

15. Step 14:

    

    That's how we got a biscuit!

16. Step 15:

    

    And here it is in the cut, the biscuit is very airy and tender! Bon appetit!
