Ingredients

For the Lemon Curd:

1 cup granulated sugar
1 tablespoon finely grated lemon zest
1/2 cup freshly squeezed lemon juice
1/2 cup (1 stick) unsalted butter, cut into pieces
4 large egg yolks

For the Bombe Assembly:

1 (8-inch) sponge cake or pound cake round, about 1-inch thick
1 quart (4 cups) high-quality vanilla bean ice cream, slightly softened

For the Swiss Meringue:

4 large egg whites, at room temperature
1 cup granulated sugar
1/4 teaspoon cream of tartar
1 teaspoon pure vanilla extract

Instructions

Prepare the Lemon Curd: In a medium, heavy-bottomed saucepan, whisk together the sugar, lemon zest, lemon juice, and butter. Cook over medium-low heat, stirring frequently, until the butter is melted and the sugar is dissolved.
In a separate small bowl, lightly beat the egg yolks. Gradually whisk about half of the hot lemon mixture into the yolks to temper them. Then, pour the yolk mixture back into the saucepan with the remaining lemon mixture.
Continue to cook over medium-low heat, whisking constantly and vigorously, for 6 to 8 minutes, or until the curd is thick enough to coat the back of a metal spoon. (Do not let it boil, or it will curdle.)
Remove from heat immediately and strain the curd through a fine-mesh sieve into a clean bowl to remove any zest or cooked egg bits. Press a piece of plastic wrap directly onto the surface of the curd to prevent a skin from forming. Let it cool to room temperature, then refrigerate until completely chilled, at least 2 hours.
Line the Mold: Select a deep, round bowl (about 2-quart capacity) that will serve as your bombe mold. Line the inside completely with a large sheet of plastic wrap, smoothing it out as much as possible to minimize wrinkles. Leave a generous overhang of plastic wrap around the edges.
Assemble the Bombe Base: Place the softened vanilla ice cream in a large bowl and stir gently until it’s spreadable but not completely melted.
Spoon about two-thirds of the softened ice cream into the bottom of the lined bowl. Use the back of a spoon or a spatula to spread it evenly and create a well or hollow in the center, coming about halfway up the sides of the bowl.
Spoon the chilled lemon curd into the hollow in the ice cream.
Top the lemon curd with the remaining one-third of the ice cream, spreading it to completely cover the curd and create a flat surface.
Place the sponge cake round directly on top of the ice cream layer, pressing down gently to adhere. Trim the cake edges if necessary so it fits snugly inside the bowl.
Fold the overhanging plastic wrap over the cake to cover it completely. Place the bowl in the freezer and freeze for at least 6 hours, or preferably overnight, until the bombe is completely firm and frozen solid.
Prepare the Meringue and Unmold: When you are ready to serve, prepare the Swiss Meringue. Fill a medium saucepan with an inch or two of water and bring it to a gentle simmer over medium heat.
In a large, heat-proof glass or metal bowl (that fits over the saucepan without touching the water), combine the egg whites, sugar, and cream of tartar.
Place the bowl over the simmering water. Whisk the egg white mixture constantly for 3 to 4 minutes, or until the sugar is completely dissolved and the mixture is warm to the touch (you can test this by rubbing a small amount between your fingers; it should not feel gritty).
Remove the bowl from the heat. Using an electric mixer fitted with the whisk attachment, beat the warm egg white mixture on medium-high speed. Start slowly and gradually increase the speed as the meringue forms soft peaks.
Continue beating until the meringue is glossy, holds stiff, stiff peaks, and has cooled to room temperature. Beat in the vanilla extract during the last minute of mixing.
Final Assembly: Remove the frozen bombe from the freezer. Unwrap the plastic wrap from the top (the cake layer). Place your serving platter upside down over the bowl. Firmly and confidently, flip both the bowl and the platter over so the bombe releases onto the platter. (If it’s stuck, you can briefly dip the outside of the bowl in a pan of warm water for a few seconds.)
Carefully lift off the bowl and peel away the plastic wrap, revealing the perfectly smooth frozen dome.
Frost and Toast: Immediately and generously cover the entire frozen bombe with the prepared Swiss Meringue. Use a spatula to create decorative swirls, peaks, or ridges. Ensure the meringue completely seals the bombe, touching the serving platter all the way around.
For the classic toasted finish, use a kitchen blowtorch to brown the meringue evenly, moving the flame continuously to prevent burning. Alternatively, you can place the entire frosted bombe under a preheated oven broiler for 1 to 2 minutes, watching extremely closely so the meringue toasts without melting the ice cream inside.
Serve: Slice the Frozen Lemon Meringue Bombe immediately with a sharp, serrated knife dipped in hot water and wiped dry between slices. Serve at once.

Tips

Make-Ahead Magic: This is the ultimate make-ahead dessert. The assembled, unfrosted bombe (still in the bowl, wrapped in plastic) can be kept in the freezer for up to 1 week. Only frost it with meringue just before serving.
Cool Your Curd: Ensure the lemon curd is fully chilled before assembling the bombe. Warm curd will immediately melt the ice cream.
Softened vs. Melted: The ice cream should be softened just enough to be spreadable. If it’s too melted, it will become icy when refrozen.
Meringue Torch: A kitchen blowtorch provides the most control and the best toasted finish for this dessert.

Storage

Once frosted and toasted, the bombe is best served immediately. Leftovers can be returned to the freezer, but the meringue texture will change and may weep slightly upon thawing. For best results, consume within 2 hours of toasting.

Serving Suggestions

Serve slices of the bombe on their own to appreciate the stunning layers.
For an extra flourish, add a few fresh raspberries or a drizzle of raspberry coulis on the plate alongside each slice to complement the tart lemon.
A sprig of fresh mint also adds a nice pop of color.
