While the exact origin of the cookie is uncertain, the traditional Dutch belief links the pepernoten to the feast of Sinterklaas, celebrated on 5 December in The Netherlands and 6 December in Germany and Belgium. This is when children receive gifts from St. Nicholas, who is partially the inspiration for the Santa Claus tradition. In Germany, the pfeffernuss is more closely associated with Christmas. The cookie has been part of European yuletide celebrations since the 1850s. The name peppernut does not mean it contains nuts, though some varieties do. The cookies are roughly the size of nuts and can be eaten by the handful, which may account for the name.
Ingredients
Throughout the years, the popularity of the pfeffernüsse has caused many bakers to create their own recipes. Though recipes differ, all contain aromatic spices - most commonly cinnamon, cloves, mace, nutmeg, cardamom, and anise. Some variations are dusted with powdered sugar, though that is not a traditional ingredient. Molasses and honey are also used to sweeten the cookies. For the dough, most versions still use 19th century ingredients such as potassium carbonate and ammonium carbonate as leavening agents to get the sticky and dense consistency of the original mixture. It is then either kneaded by hand or through the use of an electric mixer.
Regional variation
In northern Germany, pfeffernüsse are a hemispherical pastry up to two centimetres in diameter and of firm consistency.
The northern Moppen variant are larger and softer, based on a gingerbread-like dough, and have an icing glaze.
In southern Germany, the dough is made with lemon and orange peel, often also almonds.
In Saxony, they are about three centimetres, uncoated and angular.
The Netherlands has two styles. Kruidnoten are round and hard; pepernoten are angular and chewy.
Pfeffernüsse are commonly mistaken for kruidnoten or spicy nuts in English. While they are both famous holiday cookies, the kruidnoten are harder, have a darker brown color, and have a different shape. Their ingredients are more similar to the ones used in making speculaas. Russian tea cakes are also confused with pfeffernüsse, especially when dusted in powdered sugar.
