Mousse

This is a classic French-style chocolate mousse built on a pâte à bombe foundation, which is the professional-kitchen method for mousses with silky texture and real body. The technique temperate egg yolks with hot syrup over simmering water, creating a stable, glossy base that adds richness without weighing the mousse down.

This recipe is designed as a component for the Progès with Grand Marnier (a layered almond meringue and chocolate-mousse cake) but it works beautifully on its own, spooned into small glasses and chilled.

Three bowls do the work: whipped cream in one, melted chocolate folded into it, and the hot egg yolk mixture added last with a spatula. Folding (not stirring) is what keeps the air in. Stirring deflates everything and you end up with chocolate pudding instead of mousse.

Pro Tips

• Use good-quality bittersweet chocolate, at least 60 percent cocoa. Milk chocolate makes this mousse cloying and too sweet.
• Whip the cream to soft peaks only, not stiff. Stiff cream breaks when folded into warm chocolate.
• Don’t let the egg yolk and syrup mixture touch the simmering water. Keep it over the steam on a double boiler setup.
• Fold in three stages: one third of the egg mixture at first to lighten the chocolate cream, then the rest gently.

Variations

• Add 2 tablespoons Grand Marnier or Cointreau to the egg mixture for the traditional orange-chocolate version.
• Stir in 1 teaspoon espresso powder with the chocolate for a mocha mousse.
• Top with shaved dark chocolate, whipped cream, and fresh raspberries for a proper plated dessert.
