There's a tutorial on how to make shortbread cookies.  The chef demonstrates how to mix the butter and flour in a blender to blend the dough.  Then she knead the dough together to make a rectangular roll.  She sprinkles some sugar on a parchment paper and rolls the dough in it and covers it before keeping it in the refrigerator.  After cooling the dough, she takes it out and cuts them into rectangular pieces.  She places the raw cookie on a cookie sheet and bakes them.  When the cookies are done baking, she places them in an airtight plastic container for storing for future consumption.
