Scatter butter on top of flour and pulse 20 times for 1 second until flour resembles coarse meal.
Add egg mixture and pulse just until dough comes together, about 12 seconds. Turn out dough onto plastic wrap, flatten into a 6" disc and refrigerate one hour.
Remove dough from refrigerator, and roll out dough between two pieces of floured parchment paper into an 11" round.
Carefully roll dough around the rolling pin and carefully place it over a 9" tart pan wit a removable bottom. Press the dough into the flutes, patching where it's thin or breaks.
Place the tart pan into the freezer for 30 minutes.
Preheat the oven to 375 degrees F.
