About 1 hour, plus chilling time
Makes about 6 dozen cookies
Cake flour and coarse decorating sugar are available at cooking and baking supply stores, as well as at well-stocked markets.
1/2 cup (1 stick) butter, softened
1/2 cup sugar
1 egg, divided
1/2 teaspoon almond extract
1/2 teaspoon salt
1 1/2 cups (5.25 ounces) sifted cake flour
1 cup ground almonds, divided
1/2 cup coarse decorating sugar
1. In the bowl
of a stand mixer, or in a large bowl using an electric mixer, cream together the butter and sugar. Beat in the egg yolk until incorporated, then beat in the almond extract.
2. Beat in the salt,
then slowly beat in the cake flour until fully combined. Beat in one-half cup ground almonds. Wrap the dough in plastic wrap and chill thoroughly.
3. Heat the oven
to 375 degrees. On a floured surface, roll one-fourth of the dough at a time (keep the remainder covered and chilled) to form a log approximately one-half inch thick. Cut the log crosswise every inch for each cookie. Repeat until all of the dough is rolled and cut.
4. In a small bowl,
beat the egg white. In a shallow baking dish, whisk together the remaining one-half cup ground almonds with the coarse sugar.
5. Brush the surface
of each cookie lightly with egg white, then dip the surface into the coarse sugar and almond mixture.
6. Place the cookies
about 1 inch apart on an ungreased baking sheet and bake until set and golden on the bottom, about 10 to 12 minutes. Cool the cookies on a rack. Store the cookies in an airtight container. The cookies can be made up to 2 months ahead and frozen; thaw before serving.
