Dark Chocolate Muffin in an Egg

Carefully pierce the bottom of the eggs with a needle. The resulting hole should be large enough for the tip of a piping bag to fit through.

Mix egg whites and yolks in egg with a toothpick, then run out into a bowl. In doing so, collect three eggs separately.

For the salt solution, mix one liter of water with 3.5 ounces of salt. Carefully rinse the empty egg shells under running water and place them in the prepared salt solution for 30 minutes.

Now rinse the eggshells again under running water and pour boiling water over them.

Now place the eggs on paper towels with the cut out hole facing down and let them dry.

Coarsely chop the dark chocolate and melt in a saucepan with the butter. Then allow to cool.

Beat the three separately collected eggs with sugar, vanilla, and salt with a mixer until foamy. Stir the now cooled chocolate butter into it.

In a bowl, combine flour and cocoa powder and stir into the just prepared batter.
