Boil water in a small pot, add an egg and cook 10 minutes. Rinse under cold water, then peel egg and place cooked egg yolk in a bowl. (Use the cooked egg white in something else).
Smash the egg with a fork, then add the other raw egg yolk and sugar. Whisk all together well.
Now add flour, ground almonds, cinnamon, cardamom, cloves powder, salt and butter. Quickly knead it all together into a smooth dough, wrap in foil and let rest in refrigerator for 1 hour.
Preheat regular oven to 160°C.
Form the dough to a finger-like roll and cut into small pieces. Shape each piece into cherry-sized balls and place on a cookie sheet with baking paper. Bake for 12-15 minutes until light brown in color. Take out of the oven and let rest on the sheet for about 10 minutes. Then cool completely on a plate.
Coat each little button with cranberry jelly and put a second one on top, sprinkle with powdered sugar and serve.
