Homemade pie (or, let’s be honest: any pie) is always a treat, and there certainly does not need to be an excuse to have a slice. But Jan. 23 gives you an official reason to go out and indulge in apple pies, key lime pies, pecan pies and more. National Pie Day is finally upon us, so check out these three yummy recipes to try today, courtesy of allrecipes.com.

Sweet Potato Pie

Ingredients: 1 (1 pound) sweet potato, ½ cup butter, softened, 1 cup white sugar, ½ cup milk, 2 eggs, ½ teaspoon ground cinnamon, 1 teaspoon vanilla extract, 1 (9-inch) unbaked pie crust

Directions

1. Boil sweet potato whole in skin for 40 to 50 minutes, or until done. Run cold water over the sweet potato, and remove the skin.

2. Break apart sweet potato in a bowl. Add butter, and mix well with mixer. Stir in sugar, milk, eggs, nutmeg, cinnamon and vanilla. Beat on medium speed until mixture is smooth. Pour filling into an unbaked pie crust.

3. Bake at 350 degrees F (175 degrees C) for 55 to 60 minutes, or until knife inserted in center comes out clean. Pie will puff up like a soufflé, and then will sink down as it cools.

Ingredients: 1 cup white sugar, 2 tablespoons all-purpose flour, 3 tablespoons cornstarch, ¼ teaspoon salt, 1 ½ cups water, 2 lemons, juiced and zested, 2 tablespoons butter, 4 egg yolks, beaten, 1 (9-inch) pie crust, baked, 4 egg whites, 6 tablespoons white sugar

Directions

1. Preheat oven to 350 degrees F (175 degrees C).

2. To make lemon filling: In a medium saucepan, whisk together 1 cup sugar, flour, cornstarch and salt. Stir in water, lemon juice and lemon zest. Cook over medium-high heat, stirring frequently, until mixture comes to a boil. Stir in butter. Place egg yolks in a small bowl and gradually whisk in 1/2 cup of hot sugar mixture. Whisk egg yolk mixture back into remaining sugar mixture. Bring to a boil and continue to cook while stirring constantly until thick. Remove from heat. Pour filling into baked pastry shell.

To make meringue: In a large glass or metal bowl, whip egg whites until foamy. Add sugar gradually, and continue to whip until stiff peaks form. Spread meringue over pie, sealing the edges at the crust. Bake in preheated oven for 10 minutes, or until meringue is golden brown.
