Step 1

Make the pie crust by incorporating sea salt, flour, and butter until a coarse, sandy-looking meal forms. This can be done in a bowl with your hands or in a food processor. Add cold water and continue working or pulsing the mixture until a dough forms. Shape into a disc (like a hockey puck), wrap in plastic, and chill for at least 30 minutes.

Step 2

Meanwhile, preheat oven to 400 degrees. Using a fork or knife, pierce sweet potatoes several times then place directly on oven rack with a sheet pan underneath to catch any drippings. Roast for about 45 minutes or until tender then set aside to cool. You can place them in the refrigerator to speed up this process.

Step 3

Reduce oven heat to 375 degrees. Roll out chilled pie crust and place in a 9-inch pie pan. Remove excess dough from around sides of pan and crimp or style edges, as desired. Prick bottom of dough with a fork a few times then par bake for about 15 minutes then remove and decrease oven heat to 350 degrees. See notes about par baking below.

Step 4

While the crust par bakes, process cooled sweet potatoes in a food processor until smooth. Add heavy cream, butter, eggs, bourbon, brown sugar, granulated sugar, nutmeg, cinnamon, and sea salt then or pulse until uniform, pausing to scrape down sides of bowl as necessary.

Step 5

Spread filling into prepared pie crust. Return to oven and bake for about one hour and 10 minutes or until top of filling is firm to touch. Cool completely before slicing and serving.
