Mix the pie dough

1. Mix the egg yolks and milk together.

2. In the bowl of a stand mixer, add the dry ingredients and butter. Paddle for about 1 minute. You want the butter to start to mix into the flour.  It's necessary for small bits of butter to remain.

3. Add the egg yolk/milk mixture and paddle on low for 10 seconds or so. The goal is to incorporate the milk, but just barely. The real mixing, and the development of the dough, comes next.
   

4. Scoop out the dough onto a counter top. Bunch the crumbly looking dough into a pile and start at the top of the pile, push down and away into the dough. Repeat this process.

5. In between pushes, gather the dough back into a pile. As you work, the dough will start to come together and be the dough you are looking for. When it is combined, stop.

6. If you are making pies and know the diameter, measure 1 ounce of dough for every inch wide the pan. 10 inch pie pans get 10 oz of dough. Scale those portions, round them on the counter and wrap in plastic wrap. Store in the cooler for at least 4 hours, but overnight if possible.

7. Congratulations! You’ve just made pie dough.
