To make traditional pretzels you need to dip them in food grade lye before baking to give them their dark brown skin, but I can't find any available. Consequently, I looked for alternatives and learned there are 2 methods involving baking soda you can use to imitate lye. The 2 methods are:1) Boil baking soda and water and dip the pretzels in.2) Bake baking soda in the oven at 250-300 F for one hour.
