Using a stand mixer fitted with a paddle attachment, cream together butter and sugar for 2-3 minutes
1 Cup and 2 tablespoon Brown Sugar, ¼ Cup Unsalted Butter
Add eggs, one at a time, until fully incorporated
3 Large Eggs
Add flour, nutmeg and walnuts and mix until just combined making sure not to overwork the dough
¼ Cup All Purpose Flour, ½ teaspoon Nutmeg, 3 ½ Cups Ground Walnuts
Wrap dough in plastic and place in the fridge for 30-60 minutes
Lightly flour your work surface, top of the dough, and rolling pin. Then use your rolling pin to roll out dough to a 12-inch circle (about ¼-inch thick). Be sure to check if the dough is sticking to the surface below — add a small amount of flour when necessary and use a pastry scraper to prevent your dough from sticking too much.
Once your dough is rolled to the desired thickness (I prefer ¼ inch), press gently into the bottom of your buttered tart pan. Poke the bottom of the tart LIBERALLY with a fork, and place in the freezer to chill for 20-30 minutes.
Preheat the oven to 350° Fahrenheit
As this tart shell takes longer to bake than the pancetta filling, we will be par-baking the shell. This ultimately means that you will partially bake this tart dough lined with parchment paper and baking rice/beans acting as weights for 25 minutes. Remove the parchment and weights and continue as instructed below.
