Put baking paper in an oven tray, and arrange the dough diamonds on it, with a little distance between them.
Before putting them in the oven, grease them as follows:
1. For the salted salt - grease with egg white mixed with 2 tablespoons of water, sprinkle with salt and sesame / poppy seeds.
2. For the sweet icing - mix the egg whites with 1 tablespoon of honey, grease the rhombuses and sprinkle with sugar.
3. In the fasting / vegetarian version - grease with a little plain oil or olive oil and sprinkle with salt, seeds or sugar.
