Ingredients

4 ounces saltine crackers (scant 1 sleeve) 

1 stick (1/2 cup) unsalted butter, room temperature 

1/4 cup granulated sugar 

1 can (14 ounces) sweetened condensed milk 

4 large egg yolks 

1/2 cup passion-fruit puree, thawed if frozen 

4 large egg whites 

3/4 cup granulated sugar 

1/4 cup fine sanding sugar 

1/4 teaspoon kosher salt 

Preparation

Crust:Preheat oven to 350 degrees.

Pulse crackers in a food processor until finely ground. Pulse in butter and granulated sugar until combined. Firmly press into bottom and up sides of a 9-inch pie dish. Bake until golden brown, 18 to 20 minutes. Transfer to a wire rack; let cool completely.

Filling:Reduce oven temperature to 325 degrees. In a medium bowl, gently whisk together condensed milk, egg yolks, and passion-fruit puree. Pour filling into crust.

Bake until center is set but still quivers when pie dish is nudged, 15 to 17 minutes. Transfer to a wire rack; let cool completely.

Meringue Topping:Add topping shortly before serving. In the bowl of a mixer fitted with the whisk attachment, beat egg whites on medium-high speed until frothy. Increase speed to high and gradually add both sugars and salt, beating until stiff peaks form, 5 to 7 minutes. Pipe or spread meringue on pie, making sure it touches the crust all around. Lightly brown meringue with a kitchen torch.
