Ingredients

8 ounces semi-sweet chocolate, finely chopped — Use good-quality semi-sweet chocolate for the best flavor and a smooth ganache.
2/3 cup heavy cream — Heats to make the ganache and adds richness and silkiness to the mousse.
4 large egg whites — Whipped to provide the airy lift and light texture of the mousse.
1/2 cup granulated sugar — Stabilizes and sweetens the whipped egg whites for a stable meringue.
1/4 teaspoon cream of tartar — Helps stabilize the egg whites and achieve stiffer peaks.
Pinch of salt — Enhances the chocolate flavor and balances sweetness.
Note: All ingredients are used as listed. For serving suggestions, the original directions mention optional toppings.

Step-by-step Instructions

Prepare the chocolate ganache. Heat the 2/3 cup heavy cream until it is just simmering, then pour it over the 8 ounces finely chopped semi-sweet chocolate. Let sit for a minute, then stir until completely smooth. Let the ganache cool slightly before using. Tip: If the chocolate seems grainy, keep stirring gently off the heat until smooth.
Warm the egg white mixture. In a heatproof bowl set over simmering water, combine the 4 large egg whites, 1/2 cup granulated sugar, 1/4 teaspoon cream of tartar, and a pinch of salt. Whisk constantly until the mixture is warm to the touch and the sugar is dissolved.
Whip to stiff peaks. Remove the bowl from the heat and continue to whisk or use an electric mixer to whip the mixture until stiff, glossy peaks form and the meringue holds its shape.
Fold in the ganache. Gently fold the slightly cooled ganache into the meringue in batches, using a spatula and a light hand to keep as much air in the mixture as possible. Work until evenly combined and no streaks remain.
Portion and chill. Spoon the mousse into individual serving dishes or a single container. Chill in the refrigerator for at least 4 hours to set and develop flavor.
Serve. Before serving, you may finish with any suggested optional toppings described in the directions, such as a dusting or shavings. Tip: Chill serving dishes ahead for an extra refreshing presentation.
For a fun after-dessert pairing, try serving this mousse with chewy textures like chocolate marshmallow cookies.

Tips, Storage & Variations
Tips

Use a thermometer if you like precision when warming the egg whites; you want them warm, not cooked.
Chop the chocolate finely so it melts quickly and forms a glossy ganache.
Fold gently to preserve airiness; overfolding will deflate the mousse.

Storage

Refrigerate: Store covered in the refrigerator for up to 3 days.
Freezing: Freezing can slightly alter texture, so it is not recommended for best results. If freezing is necessary, freeze in airtight containers for up to 1 month and thaw in the refrigerator before serving.

Variations using only the provided ingredients

Less sweet: If you prefer a slightly less sweet finish, use a slightly smaller portion of the granulated sugar in the egg white warming stage, keeping the rest of the method the same.
Richer texture: Ensure the chocolate is high quality and fully melted into the cream to accentuate a deeper chocolate flavor without changing any other ingredient amounts.
Extra silk: Let the ganache cool to just warm before folding to preserve the lightness of the meringue while keeping the mousse smooth.
For a contrasting dessert lineup, consider pairing slices with a tray of chocolate caramel dump cake or another textured treat.

FAQ

What makes this mousse light and airy?
The whipped egg whites, stabilized with sugar and cream of tartar, trap air and create the mousse structure when folded with the ganache.
Can I use milk chocolate instead of semi-sweet?
Yes, but the flavor and sweetness will change; semi-sweet gives a balanced chocolate intensity.
Do I need to cook the egg whites fully?
No. The egg whites are warmed gently over simmering water until the sugar dissolves; they are then whipped. This is a classic method for safe, stable meringue.
How long should I chill the mousse?
Chill for at least 4 hours to allow the mousse to set and flavors to meld.
Can I make the mousse a day ahead?
Yes. Prepare up to 3 days in advance and keep covered in the refrigerator.
Is cream of tartar essential?
It helps stabilize the egg whites for stiffer peaks, but if unavailable, you can still whip the whites carefully.
