Prepare all the necessary ingredients. To make the dough fluffy, sift it through a sieve a couple of times. It is advisable to heat the milk.
In a deep bowl, mix 250 g of flour with salt and vanilla sugar. Pour milk into a bowl. Mix thoroughly until smooth. Add vegetable oil and mix the contents again. Add the yolks, turmeric and mix with a whisk or fork, whatever suits you.
Place approximately 100 g of flour in another bowl. Add the remaining amount of flour with baking powder and soda in small portions. Knead into a soft but not sticky dough. Divide it into 2 parts. Add cocoa, cardamom and cinnamon to the first, and the flour we saved for this to the other.
Sprinkle your work surface with flour. Roll out both doughs separately into a layer, cut into strips approximately 3 cm wide. Place the resulting strips close to each other, alternating colors. Using a rolling pin, roll out the strips until they come together. Wrap the resulting dough into a sausage and, holding its ends, squeeze them towards the center.
Roll out the flattened dough into a layer (preferably thick so that it turns out fluffy). Using cutters, cut out the desired shapes, place the blanks on a baking sheet covered with parchment. Leave the sweets in the oven at 175°C for 30 minutes.
Cool the finished sweets. To make the glaze, mix the egg whites, powdered sugar and lemon juice in a separate bowl. Stir until smooth. One by one, dip the sweets into the glaze. Leave the finished gingerbread cookies for an hour for the glaze to dry.
Incredibly tasty and appetizing gingerbread cookies are ready. You can sprinkle powdered sugar on top. Serve with a cup of sweet tea or coffee.
