Limpa (Swedish for "loaf") is a sweet Scandinavian rye bread, associated with Swedish cuisine. It is a yeast-leavened spice loaf, sweetened with brown sugar and molasses which comes in a large variety in regard to whether or not butter-enriched, and which spices are being used. Traditional bread spices are anise, caraway, fennel seeds, and bitter orange.
Typically baked during the Christmas season, the festive wort breads are flavored with spices like anise, caraway, and fennel seeds, and often orange rinds, raisins or sultanas, and dark beer, in addition to the wort. Its distinct taste and look is in large part due to the addition of wort to the dough, making it similar to a malt loaf. It is a typical dish for a traditional Christmas Eve smörgåsbord or julbord. Limpa bread pairs well with jams and jellies, or cream cheese.
Historically, this bread was leavened with fermented brewer's wort, hence its Swedish name vörtlimpa or vörtbröd ("wort loaf" or "wort bread"). Modern recipes sometimes still use stout beer as an ingredient.
The recipes vary, some replacing caraway with cardamom, or leaving out the orange peel; in the United States its most common form is an aromatic orange and spice loaf.
Molasses adds color to the brown bread, made with a blend of rye and other flours. Other flours blended in with the rye, depending on the recipe, can include cornmeal, whole wheat flour or all purpose flour. To add orange flavor, orange oil or orange zest can be used. Although not strictly traditional in the origin area of northern Sweden, some variations on the basic recipe may add raisins or prunes.
