Separate the eggs into egg yolks and egg whites in 2 mixing bowls.
Beat egg whites using an electric mixer or with hands until stiff peaks
In the mixing bowl with egg yolks, add in all-purpose flour, salt, milk and sparkling water.
Add and mix gently beaten egg whites into the mixture.
In a frying pan, heat up 2 tablespoons of cooking oil over medium heat. Add in a thick layer (about 0.5cm) of Kratzete batter. There should enough batter for three layers of Kratzete.
Flip the Kratzete over to another side, when one side turns slightly crispy and brown. The Kratzete will break apart, when flipped (it should be the way).
Cut Kratzete into medium size chunks.
