Better Butter Cookie

I finally got my tree up. I mean, between the never ending holiday parties (my soon to be scheduled liver transplant if I don't stop attending), physical therapy and getting myself to work on time, how can I be expected to decorate my home with shubbery in advance of the X to the Mas? Well, after hoisting my one foot wonder onto a cake stand and tuning in to Cameron Crowe's documentary, Pearl Jam Twenty (for the 18th time - just another holiday classic), I got to decorating. (It took more time to wrestle my stash of holiday decor out of my closet than to actually decorate.) And now I'm thinking about reneging on my previous post about not making cookies. Just this once. Sometimes you have to bring something to holiday parties other than another random bottle of 1996 Chateau Talbot Grand Cru Classé Saint - Julien. Am I right? When it comes to cookies, the more butter the better. Dori Greenspan's Sable (aka French butter cookie or Breton biscuit) recipe is the perfect butter cookie. Trust.

Dori Greenspan's Master Recipe for Sables
(from The New York Times)

2 sticks (8 ounces) unsalted butter (preferably high-fat, like Plugra), softened at room temperature
1/2 cup granulated sugar
1/4 cup confectioners' sugar, sifted before measuring
1/2 teaspoon salt, preferably sea salt
2 large egg yolks, preferably at room temperature
2 cups all-purpose flour For the decoration (optional):
1 egg yolk
Crystal or dazzle sugar

1. Working in a mixer fitted with a paddle attachment, beat the butter at medium speed until it is smooth and very creamy. Add the sugars and salt and continue to beat until smooth and velvety, not fluffy and airy, about 1 minute. Reduce the mixer speed to low and beat in 2 egg yolks, again beating until well blended.

2. Turn off the mixer, pour in the flour, drape a kitchen towel over the mixer and pulse the mixer about 5 times at low speed for 1 or 2 seconds each time. Take a peek; if there is still a lot of flour on the surface of the dough, pulse a couple of more times; if not, remove the towel. Continuing at low speed, stir for about 30 seconds more, just until the flour disappears into the dough and the dough looks uniformly moist. If you still have some flour on the bottom of the bowl, stop mixing and use a rubber spatula to work the rest of it into the dough. (The dough will not come together in a ball -- and it shouldn't. You want to work the dough as little as possible. What you're aiming for is a soft, moist, clumpy dough. When pinched, it should feel a little like Play-Doh.)

3. Scrape the dough onto a work surface, gather it into a ball and divide it in half. Shape each piece into a smooth log about 9 inches long (it's easiest to work on a piece of plastic wrap and use the plastic to help form the log). Wrap the logs well and chill them for at least 2 hours. The dough may be kept in the refrigerator for up to 3 days or frozen for up to 2 months.

4. When ready to bake, center a rack in the oven and preheat the oven to 350˚F. Line a baking sheet with a silicone baking mat or parchment paper and keep it at the ready.

5. To decorate the edges of the sables, whisk the egg yolk until smooth. Place one log of chilled dough on a piece of waxed paper and brush it with yolk (the glue), and then sprinkle the entire surface of the log with sugar. Trim the ends of the roll if they are ragged and slice the log into 1/3-inch-thick cookies.

6. Place the rounds on the baking sheet, leaving an inch of space between each cookie, and bake for 17 to 20 minutes, rotating the baking sheet at the halfway point. When properly baked, the cookies will be light brown on the bottom, lightly golden around the edges and pale on top. Let the cookies rest 1 or 2 minutes before carefully lifting them onto a cooling rack with a wide metal spatula. Repeat with the remaining log of dough. (Make sure the sheet is cool before baking each batch.)

Variations
Lemon Sables: Before mixing the butter and sugar together, pour the sugar in a bowl with the grated zest of 1 to 1 1/2 lemons. Work the zest and sugar together with your fingertips until the mixture is moist and aromatic, then cream it with the butter in the mixer.

Parmesan Sables: Replace sugars with 3/4 cup very finely grated Parmesan added to the beaten butter. A few grains of fleur de sel may be gently pressed into the top of each sable before the baking sheet is slipped into the oven.
