Lye roll
Alkaline-dipped baked rolls, a German and Alsatian specialty.
Lye rolls are a baked good found in Germany (particularly Bavaria and Swabia), the French region of Alsace, Switzerland, and Austria. The rolls are made by dipping them in a lye solution before baking. In German, the term *Laugengebäck* refers to any pastry treated this way, with the pretzel being the most iconic form. Regional names for the rolls include *Laugensemmel* or *Kastanie* in Bavaria, *Laugeweckle* or *Laugestängle* in Swabia, and *Laugenwecken*, *Laugenbrötchen*, or *Laugenstange* elsewhere in Germany; *Laugenweckerl* in Austria; and *Silserli* or *Laugenbrötli* in Switzerland. In parts of Asia, they are also called laugen rolls. In France, the lye roll is known as a *mauricette*, created by Paul Poulaillon when he opened the first Poulaillon bakery in Alsace in 1973. It was trademarked in 1985 under the alternate name *Moricette*, and the original lard was later replaced with rapeseed oil.
To achieve the characteristic browned crust, the roll must be coated with a high-pH (alkaline) solution before baking; a higher pH produces a stronger Maillard reaction. Lye—either sodium hydroxide (NaOH) or potassium hydroxide (KOH)—is the most common and strongest alkaline agent for this purpose. However, a baking soda or washing soda solution, which is safer and easier to handle, can produce a similar but less pronounced effect. The same lye solution is used for pretzels, which outside German-speaking countries are often the only baked goods commonly glazed this way.
Lye rolls and pretzels are usually topped with salt, ideally pretzel salt—a large-grained salt made from compressed smaller particles, which resists moisture absorption and stays hard. As a snack, lye rolls may also be sold as sandwiches or topped with baked cheese, though this is a newer and less common practice. Typically, they are cut in half and buttered, much like large soft pretzels in Germany and Switzerland. Other toppings now include poppy, sesame, and other seeds as alternatives to salt. In Germany, lye rolls come in various shapes and sizes, each with its own name: for instance, *Laugenstange* refers to long oval rolls, while *Laugenbrötchen* are small round rolls.
Other foods prepared with lye include lutefisk, hominy, and alkaline noodles.

Lore & Background
Lye rolls are produced by coating bread rolls with a high-pH alkaline solution before baking, which triggers the Maillard reaction for a characteristic browning effect. The most common agent is lye (sodium hydroxide or potassium hydroxide), but baking soda or washing soda solutions can be used, though they produce a less pronounced reaction. The same solution is used for pretzels, which outside German-speaking countries are often the only baked food commonly glazed with lye.
Reader's Guide
Lye rolls are typically covered with salt, preferably pretzel salt, a large-grained salt made from compressed smaller particles that reduces moisture absorption and hardness. They may also be sold as sandwiches or covered with baked cheese, though this is a more recent development. Traditionally, they are cut in half and buttered, as large soft pretzels often are in Germany and Switzerland. Other toppings include poppy, sesame, and other seeds as alternatives to salt. In Germany, they appear in many shapes and forms, such as Laugenstange (long oval rolls) and Laugenbrötchen (small round rolls). The French mauricette was invented by Paul Poulaillon in 1973 and later registered as a trademark with the alternate name Moricette in 1985; lard was replaced by rapeseed oil in that product.
