A type of bread flavored with walnuts that are chopped or ground. There are many variations of walnut bread, which is British in origin. Some are made with a basic yeast dough of all-purpose flour or bread flour studded with walnuts, while other varieties are prepared with dough enriched with butter and milk and flavored with brown sugar and spices in addition to the walnuts. Some of the more elaborate sweetened versions are braided or rolled and are served as a dessert bread, while the unsweetened basic dough versions are often shaped into a pan loaf or bloomer and are excellent when served with strongly flavored cheeses. The French version of walnut bread is called Pain aux Noix.
