Sift the flour
and salt into a medium bowl. Use a wooden spoon to
beat the butter and marzipan in a large bowl until
well blended.
Beat in the brown sugar. Mix in
the dry ingredients to form a stiff dough. Press
the dough into a disk, wrap in plastic wrap, and
refrigerate for 30 minutes.
Preheat the oven to
350°F/180°C/gas 4. Line two cookie sheets
with parchment paper. Discard the plastic wrap.
Roll out the dough on a lightly floured surface to a
thickness of 1/4 inch (5 mm). Cut into 3/4 x
2 1/2-inch (2 x 6-cm) strips.
Gather the dough scraps,
re-roll, and continue cutting out cookies until all
the dough is used.
Use a spatula to transfer the
cookies to the prepared cookie sheets, placing them
1 inch (2.5 cm) apart.
Sprinkle with the raw
sugar. Bake for 10-12 minutes, or until golden
brown. Transfer to racks to cool.
