These shortbreadlike cookies are just as delicious filled with another flavor of jam or preserves. We suggest using only butter for these delectable treats. Its flavor is unmatched by any substitute.
Pat each roll of dough into a strip 2 inches wide. Press down the center of each strip with the back of a small spoon to create a 1-inch-wide indentation.
Bake the strips, transfer to a wire rack, then immediately fill the indentations with preserves. While the strips are still warm, cut them diagonally with a sharp knife into 1-inch-wide pieces. Sprinkle with nuts and cool completely.
