Then divide the dough in small portions and form into the desired shape (long thin strands or round rolls or pretzel shaped) and let it rest for a few minutes.
Prepare a lye solution and dip the rolls in it for about 30 seconds, place them on a baking sheet and preheat the oven to 180`Celcius
You can sprinkle some salt or grated cheese or different kinds of seeds on top. Bake for around 25 minutes.
Please check your rolls, as every oven is a bit different!

TAKE CAUTION: If you are not familiar with the process of making a lye solution and the handling of it, please inform yourself beforehand. Here I found two great instructions, that would be very helpful if you bake Pretzels or lye rolls for the first time!

"Make the lye solution. Weigh out 30 grams, about one ounce, of the food-grade lye (NaOH) pellets and add it to one liter of water, about one quart. Do not add water to the small pile of lye, you will cause a violent reaction as the lye releases heat. Stir until dissolved.Can you use something else besides lye? Yes and no. You can dunk the pretzels into hot water with sodium carbonate..."
