This BIG cookie is easy to prepare and even easier to share since you juts need to break off some pieces and eat!!
3 3/4 cups sifted all-purpose flour
1 1/4 cups granulated sugar
1/2 tsp salt
2 sticks plus 2 Tbsp salted chilled butter, cut into small cubes
1 large egg
3 TBSp dark rum
1 large egg yolk
Preheat oven to 350 F. Place flour, sugar and salt in the bowl of a food processor and pulse 6 times.
Add the butter and process until the mixture is granular in texture.
Whisk the egg and rum in a small bowl, add to food processor, and process just until a ball forms.
It it is still too dry to form a ball, add 1 Tbsp of ice water at time until it comes together into a ball.
Place the dough on a large piece of plastic wrap. Press it down with the palms of your hands. Transfer to a baking sheet, removing the plastic wrap and continue shaping and pressing the disk until it is 1/2 inch thick and approximately 10-11 inches across. Pinch all the way around. Beat the egg yolk and brush it across the top.
Drag the tines of a fork from one end to the other several times to create a large criss-cross pattern.
Bake for 25-35 minutes, until golden.
Allow to cool for a t least 20 minutes on the baking sheet, then carefully slip it off onto a large round plate or tray.
To serve, present the whole cookie and let people break off pieces.
