Notes about the recipe: This is my marathon-running dad's favorite cake (and he's always watching what he eats). I was asked to make Mayor Daley's birthday cake after he was having some heart concerns, so an orange version of this was the winner. One of the guests to arrive late was President Bill Clinton, who I got to sit with and talk to.
- 1 1/2 cups egg whites (from about 1 dozen eggs), at room temperature
- 1 1/4 teaspoons cream of tartar
- 1/2 teaspoon salt
- 1 1/2 cups sugar
- 2 to 3 teaspoons hot water
- 1 tablespoon instant coffee or espresso
- 1 1/8 cup sifted cake flour
- 1 teaspoon pure vanilla extract
- 1/4 cup espresso
- 8 ounces confectioners' sugar, sifted
- Serving Suggestion: Vanilla frozen yogurt
Make the Cake: Preheat the oven to 375 degrees F.
In a mixer fitted with a whisk attachment (or using a hand mixer), whip the egg whites until foamy. Add the cream of tartar and salt and continue whipping until soft peaks form. With the mixer running, gradually add 1 cup of the sugar and continue whipping until stiff and the sugar has dissolved, about 30 seconds.
In a small bowl, stir together the hot water and instant coffee to make coffee extract.
Fold the flour mixture into the egg whites in batches; then fold in the vanilla and dissolved coffee.
Cool by turning the cake (in the pan) upside down, propped on top of a bottle until it cools to room temperature. Run a long, sharp knife blade, or a butter knife, around the cake to loosen, then knock the cake out onto a plate or work it out with your fingers. The outside crumb of the cake will remain in the pan; exposing the white cake underneath.
Make the Glaze: Stir the ingredients together until smooth. Add more liquid if too thick or more sugar if too thin. Pour glaze over the top of the cake, letting it drip down naturally. Let glaze set until hard, at least 30 minutes before serving. Serve with vanilla frozen yogurt, so you have a cappuccino in your mouth.
