NOTE: This recipe calls for raw egg yolks, which the U.S. government has named as a potentially hazardous food. Raw eggs should not be eaten by young children, pregnant women, the elderly or those with a compromised immune system.
Pasteurized egg whites are available at some stores. A common brand name is Eggology.
1 1/2 cups (3 sticks) unsalted butter, softened
18 ounces (3 cup) semisweet chocolate chips
3/4 cup amaretto liqueur
1/3 cup powdered sugar
4 egg yolks
12 ounces toasted, ground almonds, about 2 cup
4 pasteurized egg whites
Dash cream of tartar
12 shortbread cookies (such as Lorna Doone), or
as needed to complete 2 layers
Whipped cream and more almonds for garnish
Line a 9 x 5-inch loaf pan with clear plastic wrap; set aside.
Gently melt 1/2 cup butter (saving remaining 2 sticks) in a heavy saucepan set over low heat (do not allow to hiss or brown). Remove from heat. Stir in chocolate chips until melted and smooth. Stir in amaretto. Cool to room temperature.
Beat remaining 1 cup (2 sticks) butter with an electric mixer. Gradually add powdered sugar, scraping inside of bowl as you do. Add egg yolks 1 at a time, scraping bowl and beating well after each addition.
Beat in cooled chocolate mixture until completely combined. Stir in ground almonds.
In a medium bowl with clean beaters, beat the egg whites and cream of tartar. Begin on low speed, and gradually increase speed until soft, billowing peaks form. Gently fold a spoonful of egg whites into chocolate mixture, to lighten. Fold in remaining egg whites, until mixture is light, foamy and evenly combined.
(To fold, hold large rubber spatula like a knife. "Cut" through the center of mixture, reaching down to the bottom of bowl. Scrape up from bottom of bowl, and pull over the top of the mixture. Give bowl a quarter-turn and repeat. When finished, mixture will be a thick, creamy mousse - not soupy.)
Spread a layer of chocolate mousse in bottom of loaf pan; top with a layer of cookies. Repeat, ending last layer with chocolate batter. Refrigerate overnight. Invert onto plate. Slice to serve. Garnish each slice with whipped cream and additional roasted almonds.
Serves 12, approximately.
To roast almonds: Spread almonds on a cookie sheet and bake in a 350 degree F oven until thoroughly browned, about 12 to 20 minutes. Stir occasionally to brown evenly. Grind almonds in a food processor or, in batches, in a coffee grinder.
