Ground nuts can be a winning alternative to wheat flour. Almond meal proves the point as the basis for the crunchy, sweet crust of this chocolate custard tart.
1. To make Crust: Beat egg white with electric mixer until pale and frothy. Beat in sugar and salt, then almond meal, cornstarch, butter, vanilla, and almond extract (if using). Chill 15 minutes.
2. Roll out dough on work surface dusted with cornstarch or between two pieces of wax paper or plastic wrap. Coat 9-inch pie pan with cooking spray. Press Crust into prepared pan, and trim edges.
3. Preheat oven to 350°F. Line Crust with foil or parchment paper, and fill with dried beans. Parbake Crust 8 minutes.
4. To make Filling: toast almond slivers on baking sheet in oven 5 minutes.
5. Bring evaporated milk, coconut milk, and sugar to a boil in saucepan. Place chopped chocolate in heat-proof bowl, pour milk mixture over top, and whisk until chocolate is melted. Return to saucepan, and return to a boil.
6. Whisk eggs in same heat-proof bowl. Whisk chocolate mixture into eggs. Pour hot chocolate mixture into Crust. Bake 10 minutes, or until filling is set. Cool, then sprinkle with toasted almonds.
