    Soft Pretzels Made the Old-Fashioned Way

    German pretzel

    Soft pretzels made the old-fashioned way, dipped in lye and sprinkled with salt, make the best tasting pretzels.

    In earlier times before the population was mostly literate, pictographic signs explained at a glance what the shop sold. Walk down the street in any small town in Germany and you will find a wooden sign hanging perpendicular to the road. A large pretzel literally showed you where to find the local bakery. Pretzels are one of the most beloved bakery items, especially in southern Germany.

    Why the Lye?

    The German pretzel here is known as the "Laugenbrezel" or lye pretzel. The burning question is who came up with the idea to dunk them in lye?

    The history is hard to know for sure. Lye was a common household item, used for kitchen cleaning and food preparation. Olives are cured in a lye bath, hominy and lutefisk are soaked in it, soups and fish were spiced with it, soap is made with it, and even today, lye is used to open clogged drains whenever Drain-O is poured down the sink.

    Form Balls of Dough

    Start with a good pretzel dough recipe. Once the dough has been made, divide the risen dough into twelve dough balls, about 2 ounces apiece. 

    Then form each dough ball into thin foot-long strands and let rest a few minutes. This relaxes the gluten and lets the dough be rolled even thinner. Spritz with water, if necessary, to make the dough more manageable.

    Once the dough has relaxed, you can roll the strands even thinner. Leave them thick in the middle. Form into a pretzel shape and use water to make the ends stick to the middle. Place on a wax paper-lined pan and put them in the refrigerator for one hour.

    The traditional German shape trisects the loop of dough to form three, evenly sized holes.

    You don't have to twist them arduously by hand. Professional pretzel bakers can grab the ends, flip once horizontally, once vertically and their pretzels are perfectly formed. Rank amateurs have to wrestle them into shape. Once you get the hang of it, your pretzels will look great.

    Make a Solution to Dunk the Pretzels

    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.

    If you want to avoid lye, you can dunk the pretzels into hot water with sodium carbonate (not sodium bicarbonate) in it,  but according to the connoisseurs, they won't taste the same. Baking soda won't give you quite the same crust and boiling water makes a pretzel-shaped bagel.

    Dunk the Pretzels in Lye

    Dunk the cold pretzels in the 3% lye solution for 30 seconds. Drain them well and then place on a greased baking sheet or a sheet lined with parchment paper.

    Lye is also known as caustic soda, NaOH or sodium hydroxide and is considered a hazardous material. It absorbs water from the air, so the container must be kept airtight and out of reach of children. If it gets on your skin it will feel soapy. If left on your skin it starts to dissolve the epidermis and causes a burn. You can wash it off with running water or soap and water. It will burn very quickly if it splashes in your eyes.

    USE EXTREME CAUTION: If you plan on using lye to make pretzels or soap or anything else, treat the area you use it as a laboratory area and clean before and after you are done using it. Always use gloves and safety glasses. Wearing long sleeves, pants, and close-toed shoes is recommended.

    You should dispose of lye according to your county and state hazardous chemical codes. This might include dilution of the solution with water, neutralization with an acid and subsequent dilution, or taking the waste to a disposal facility.

    Salt and Cut the Pretzels Before Baking

    Sprinkle with salt and cut a deep slit horizontally through the thickest part of the pretzel. Let them rest for a few minutes while the oven heats up to 375°F.

    The distinct pretzel shape has been around for over 1000 years and can be made out of many types of dough. It arose from a simple ring of dough, which helps the bread bake evenly. They have been associated with Christianity and often used to bring luck or blessings to a person. In Germany, the pretzel is most often seen around the New Year, "Karneval" and Easter.

    The difference between Swabian and Bavarian pretzels is in the shape. Bavarian pretzels are about the same thickness all the way around. Swabian pretzels are thick in the middle, with a slit through the thickest part, and thin and crispy at the ends, or twisted part.

    Bake the pretzels for 20 to 25 minutes at 375°F. Pretzels are at their best when eaten on the same day they were baked. You may also freeze them and reheat in the oven.
