½cupunsalted butter, cold and cut into cubes (113 grams)
3-5tablespoonsice cold water
1cuplight corn syrup(312 grams)
½cuppacked light or dark brown sugar(105 grams)
¼cupunsalted butter, melted (56 grams)
1cupsweetened flaked coconut, toasted (85 grams)
1cupbittersweet or dark chocolate chips(170 grams)
2cupsshelled pecans(225 grams)
To make the crust:
Combine the flour, sugar, and salt in a medium bowl. Add the cubed butter and work into the dry ingredients with a pastry blender, just until the smallest pieces are the size of peas. Some larger chunks are okay.
Add 3 tablespoons of the cold water and work into the flour/butter mixture with a spatula and then your hands, kneading very minimally to bring it together into a ball. Add more water a tablespoon at a time as needed.
Flatten into a disk, wrap in plastic and chill for at least 2 hours and up to 5 days in the fridge or (double wrapped) in the freezer for up to 2 months.
To assemble pie:
Preheat oven to 350°F.
On a lightly floured surface, let the pie crust sit at room temperature for about 5 minutes. Roll out into a rough 12-inch circle, adding more flour to your work surface as necessary.
Transfer dough to a 9x2-inch pie dish and trim edges to 1 inch. Tuck the edges into the pie dish and crimp as desired. Chill in the freezer while you prepare the filling.
Whisk together the corn syrup, brown sugar, melted butter, eggs, vanilla, and salt. Stir in the toasted coconut, chocolate chips, and pecans. Pour filling into the pie crust, and spread it out so the top is even.
Place pie on a sheet pan (to catch any drips and make transferring in and out of the oven easier) and bake until the top is golden and center jiggles only a little when gently nudged, 45-55 minutes. If the top browns too quickly, cover with foil.
Serve either warm or at room temperature. Pie will slice more cleanly after it's been chilled. Serve with whipped cream if desired.
To toast coconut: Spread out in a single layer on a sheet pan. Toast in a 350 degree oven for 8-10 minutes, stirring once. Let cool.
