SWEET-POTATO PIE WITH GINGERSNAP PECAN CRUST

Sweet-Potato Pie with Gingersnap Pecan Crust image

In many sweet-potato pies, the ginger and spices overwhelm the flavor of the potatoes. This version plays to the flavor of the tubers; a little spicy nuttiness from the gingersnap pecan crust just emphasizes the pie's luscious creaminess. It is perfectly normal for the surface of a custardy pie, like this one, to crack in the course of baking and cooling-the pie will taste no less delicious.

Ingredients

For crust:
5 tablespoons unsalted butter, melted, plus additional for buttering pie plate
Flour for dusting
1 cup finely crushed gingersnap cookies (5 ounces; 20 2-inch cookies)
1/2 cup finely chopped pecans (2 ounces), toasted
2 tablespoons sugar
1/8 teaspoon salt
For filling:
2 lb sweet potatoes (4 medium)
1/2 cup sugar
1/3 cup water
3 large eggs
1/2 teaspoon cinnamon
1/4 teaspoon salt
2/3 cup whole milk
1 tablespoon dark rum
1/2 teaspoon vanilla
Accompaniments: lightly sweetened whipped cream and toasted pecans
Special Equipment
a 10-inch glass or ceramic pie plate (6-cup capacity)

Steps:

Make crust:
Put oven rack in middle position and preheat oven to 350°F. Butter and flour pie plate, knocking out excess flour.
Toss together all crust ingredients in a bowl with a fork until crumbs are moistened, then press evenly over bottom and up side of pie plate. Bake crust 6 minutes, then cool on a rack.
Make filling:
Increase oven temperature to 400°F.
Prick each sweet potato once with a fork. Roast in a foil-lined shallow baking pan until tender, about 1 hour. Remove from oven and reduce oven temperature to 375°F. Halve potatoes lengthwise and cool.
While potatoes cool, cook sugar in a dry 8-inch heavy skillet over moderate heat, undisturbed, until it begins to melt. Continue to cook, stirring occasionally with a fork, until sugar melts into a deep golden caramel. Remove from heat. Carefully pour water down side of skillet (mixture will bubble and steam vigorously), then return to heat and simmer, stirring, until hardened caramel is completely dissolved. Remove from heat.
When potatoes are cool enough to handle, peel, then cut away any eyes or dark spots. Purée potatoes in a food processor until smooth, then add eggs, cinnamon, and salt and blend until smooth. Add milk, caramel, rum, and vanilla, and blend until combined well.
Pour filling into crust. Bake until filling 2 inches from edge is slightly puffed and center trembles slightly when gently shaken, 40 to 50 minutes (top may crack; filling will continue to set as it cools). If the crust begins to brown too much before the filling is done, crimp a ring of foil or use a pie shield to protect it. Cool pie on rack about 1 hour.
Serve warm or at room temperature.
