Chocolate-Raspberry Cream Pie

1. 1Place the raspberries, sugar, and salt in a medium, nonreactive saucepan and stir until the raspberries are coated in sugar. Mash with a potato masher until about half of the berries are completely smashed but some medium-sized chunks remain.
2. 2Place the pan over medium-high heat and cook, stirring occasionally, until bubbles form along the edge, about 3 minutes. Add the lime zest and juice, stir to combine, and bring to a full boil, about 2 minutes. Reduce the heat to medium and simmer, stirring occasionally, until the mixture has thickened and the raspberries are falling apart, about 8 minutes more. Meanwhile, place a fine-mesh strainer over a medium heatproof bowl and set aside.
3. 3Pour the raspberry mixture into the strainer. Using a rubber spatula, push on the solids and scrape the underside of the strainer until all of the liquid has been extracted (you should have about 1 cup); discard the contents of the strainer. Set the syrup aside to cool for at least 30 minutes.
4. 4Refrigerate the syrup uncovered until cold, at least 1 hour. (If not using right away, cover and refrigerate for up to 1 week.) Meanwhile, make the crust and chocolate layer.

For the crust and chocolate layer:

1. 1Heat the oven to 350°F and arrange a rack in the middle.
2. 2Break the crackers into rough 2-inch pieces and place in a food processor fitted with a blade attachment. Process into fine crumbs (you should have about 2 cups), about 30 seconds. Stop the motor, add the melted butter, and pulse to combine, about 5 (1-second) pulses. (Alternatively, place the crackers in a resealable plastic bag, press out the air, and seal. Using a rolling pin, smash into uniform fine crumbs. Transfer to a medium bowl, add the melted butter, and mix until evenly combined.)
3. 3Pour the crumb mixture into a 9-inch pie plate and, using the bottom of a cup or your fingers, press firmly and evenly into the bottom and up the sides.
4. 4Bake until fragrant and slightly darkened in color, about 8 minutes. Remove the pie plate to a wire rack and let cool at least 15 minutes.
5. 5Place the chocolate chips and cream in a small saucepan. Cook over medium-low heat, stirring continually until the chocolate is just melted and the mixture is smooth, about 4 to 5 minutes. Pour into the cooled crust and spread into an even layer. Freeze until the chocolate layer is set, about 30 minutes. Remove from the freezer while you make the raspberry cream filling.

To make the raspberry cream filling and assemble:

1. 1Chill the bowl of a stand mixer and the whisk attachment in the freezer for 10 minutes.
2. 2Add the cream, sugar, and vanilla to the bowl and whisk on high speed until medium peaks form, about 1 1/2 to 2 minutes. (Alternatively, you can use a hand whisk and a large chilled bowl. Whisk until medium peaks form, about 3 to 4 minutes.)
3. 3Stop the mixer and add the chilled raspberry syrup. Return the mixer to high speed and whisk until firm peaks form, about 30 seconds to 1 minute (or 2 to 3 minutes if whisking by hand). Remove the bowl from the mixer and, using a rubber spatula, scrape along the bottom and stir gently to incorporate any white streaks. Transfer the raspberry cream filling to the prepared crust and spread it into an even layer.
4. 4Arrange the whole raspberries stem-side down in a decorative pattern on top of the filling. Set the pie aside.
5. 5Place the chocolate chips in a small saucepan over low heat, stirring occasionally until they’re melted and smooth. (Alternatively, melt the chocolate in the microwave, stirring at 30-second intervals to avoid burning.) Dip a fork into the melted chocolate and drizzle it over the pie in a zigzag pattern. Place the pie in the refrigerator uncovered for at least 15 minutes and up to 2 hours before serving.
