Pretzels can easily be made by yourself with this recipe:
500g flour, 1 packet dry yeast, 1 tablespoon sugar, 1 tablespoon salt, 1/4 litre warm water
3-4 litres of water and 3-4 tablespoons of baking soda
When you have, coarse salt to sprinkle on the pretzels
Mix 100g flour with yeast, sugar, add 100 ml warm water. Cover it and wait vor 30 minutes. Then add the rest flour, water and salt. Then knead. Cover and let rest for about 60 minutes until the volume has doubled (You can also leave the dough in the fridge overnight).
Knead dough again and form into roll (or two). Cut 10-12 pieces and roll these into long strands. Now form pretzels or rolls from them.
Here you can learn, how to do:
Boil water in a pot with baking soda. Place the pretzels one after the other in the boiling water and boil for 10-20 sec. Lift out and drain a little.
Place the pretzels on a baking paper and add coarse salt. Bake at 200°C for 20-30 minutes. Check in beetween!
