Beat the egg whites into hard snow, then add the sugar, salt, cardamom and vanilla sugar and beat for a few minutes to make the snow silky and harder.
Then stir in the almonds and place the mass in the refrigerator for half an hour to 1 hour. Then mix it and use a table spoon to make pile cookies on a baking tray with baking paper. (or pipe them)
Leave some space between them for the cookies to spread and grow.
Bake at 130 degrees Celsius for 40 minutes to make the cookies rise and get a light brown color.
When cooled, they are hardened and can be removed from baking paper with ease.
