Put the almonds in a small pot with a little water, bring to the boil, drain and let it cool down for 2-3 minutes. Peel the skin. Halve the almonds lengthwise. Dice the marzipan and place in a mixing bowl. Separate the egg. Mix icing sugar and flour and sieve onto the marzipan. Add the egg white and knead with the dough hooks of the hand mixer.
Whisk egg yolk and cream with a fork. Form approx. 36 balls from the marzipan mixture with wet hands. Place on a baking tray lined with baking paper. Brush with the whisked egg yolk and press 3 almond halves on each side of the balls. Bake in the preheated oven (electric: 175 °C/ gas: level 2) for 15-20 minutes. Remove from the oven and allow to cool on a rack. Dust with icing sugar as desired
