Step 1

Pulse flours, sugar, and salt in food processor to mix.

Step 2

Add chilled butter pieces.  Pulse 3-4 times until butter is still the size of pinto beans.  Dump mixture out into a bowl.  Place the bowl in the fridge for about 15 minutes to get it cold.

Step 3

Remove from fridge.  Add vinegar and the ice water.  Gently, carefully mix the dough just until it seems well distributed.  It will be very craggy and may have dry flour bits.

Step 4

Dump the dough onto a piece of parchment or plastic wrap.  Form dough together, as best as you can, into about a 4 x 4-inch square.  Wrap up and place in the fridge for 45 minutes.

Step 5

Roll out into a rectangle approximately 5 x  Fold the pastry in thirds widthwise, like a business letter, resulting in 3 layers of dough.

Step 6

Turn the short end toward you and repeat step 6 two more times.

Step 7

After the third turn fold the dough in half.  Refrigerate for one hour or up to 3 days.

Step 8

Rest the dough for 20 minutes at room temperature before rolling out.

Step 9

Set oven to 425 degrees.  If using a pizza stone or cast iron pan, place in the oven now while preheating.

Step 10

Saute’ kale, garlic and leeks in olive oil with the 1/4 teaspoon of salt over medium heat for about 8 minutes.  Turn off heat and cover with a lid for 5-10 more minutes until tender.  Add sage and parsley.  Set aside.

Step 11

Meanwhile in another bowl combine eggs, anchovy paste, dijon, lemon juice, salt, and black pepper.

Step 12

Roll out dough on a piece of parchment to 1/8 of an inch thick and in an approximate 14″ circle. Trim the edges of the dough with a sharp knife to allow them to puff up.

Step 13

Spread mascarpone cheese on the rolled out circle, all but the outer 2 inches.

Step 14

Lay filling and grated gruyere cheese on top of the mascarpone.

Step 15

Whisk together egg wash.  Brush the outside 2 inches of dough with the wash.

Step 16

Fold the outer 2 inches of dough in over the filling, overlapping dough every 2-3 inches gently pinching just enough to secure.

Step 17

Pour the seasoned beaten egg mixture evenly over the filling.

Step 18

Brush top of the crust with egg wash.

Step 19

Carefully transfer, lifting the parchment and galette onto the stone, cast iron or baking sheet.  Sliding onto a pizza peel or cutting board can help with the transfer.

Step 20

Bake 10 minutes then turn oven down to 375 and bake another 25-35 minutes until puffed and the crust is golden.  Cool 20 minutes before cutting.
