1. Mix all the ingredients (except butter) in a bowl to obtain a soft and homogeneous paste. Make a ball of it and place it to rest for 30min.
2. Then make the puff pastry. To do this, roll out your dough in the shape of a square (to help you, you can draw a cross on your ball of dough and stretch it by the 4 corners).
3. Spread the butter fresh out of the fridge in a squared shape to a thickness of about 1cm. Place it on top of the dough in the opposite corner and close the dough at each corner.
4. Spread the dough again, about 40cm long and 20cm wide.
5. Fold the dough in at both ends and fold it in half again. Leave your dough to rest gently in a cloth for 2 hours in the fridge.
6. Roll out the dough again and fold the dough into 4 and leave to rest in the fridge for at least 2 hours.
7. Finally, spread the dough over a width of 10cm, twist and shape it into the shape of a pretzel.
8. Leave to rest for 2 hours, add your favourite ingredients (almonds, chocolate ...) and bake for 15-20 minutes at 220°C.
Enjoy your meal!
