I love making these tiny French butter cookies at Christmas. They are not difficult, but a tad laborious. I realize I skipped photographing a step - the slicing of the dough. Such is the case, late at night, when one's hands are awfully sticky. My apologies...
Step one: Hurl partially formed dough onto a parchment sheet.
Step two: Try to persuade dough to conform to the sized paper under the parchment.
Step three: Try harder... use rolling pin "persuasion."
Step four Cut dough into strips, and alternate.
Step five: repeat, using eggwash "glue" and reverse the colour scheme. Repeat again, reversing colours once more for the final layer.
Step six: chill and thinly slice the completed cookie logs. (You can wrap them well in waxed paper or parchment, and freeze them for several months. Defrost slightly before slicing, or they will be shattery.)
Step seven: bake for 8 minutes.
