1. Mix the flour, baking powder, sugar, and salt in a large bowl. Add the orange zest, butter, eggs, and rum and mix everything with a fork, then knead with your hands until you get a smooth dough. Shape into a ball, flatten it, and wrap in plastic wrap. Place in the fridge for about 30 minutes.

2. Shape the chilled dough into a log and cut off thin slices. Shape into small balls (bit smaller than a walnut) – make sure they are very smooth – and then shape into drops. Set aside. Mix the sugar and ground cinnamon in a small bowl and set aside as well.

3. Add fat/oil to a small pot – it should be enough so the dough pieces can take a swim. Heat up to a temperature of about 345°F (175°C) – check with a kitchen thermometer* so the fat/oil doesn’t get too hot. Add the dough pieces in small batches and deep-fry until golden brown all around. Remove the Mutzenmandeln from the fat/oil with a slotted spoon*, drain briefly on a piece of kitchen paper, then roll in the cinnamon-sugar mix while still hot. Repeat with the rest of the dough pieces – check the temperature of the fat/oil from time to time. Serve the Mutzenmandeln as soon as possible – they are best when still warm.
