Recipe

Step 1: Prepare the cake pan.

Step 2: For a tube pan, butter the inside. Mix the flour and cocoa together and use this mixture to flour the pan. For a springform pan, butter the inside. Then line with a circle of buttered baking parchment for the bottom and a strip of buttered parchment for the sides.

Step 3: Boil in unsalted water 2 unpeeled medium sized potatoes or 3 small potatoes. Drain. Cool completely, peel, rice or sieve.

Step 4: Preheat oven to 350°F.

Step 5: Grate the chocolate. The finer the better.

Step 6: Sift the flour once by itself. Then sift it a second time with the cinnamon, baking powder and salt.

Step 7: Cream the butter with the sugar until light and fluffy.

Step 8: Separate the eggs. Add the yolks (one at a time) to the creamed mixture beating well after each one.

Step 9: Stir in the grated chocolate and ground almonds. Add the sieved potato and stir again.

Step 10: Add the flour alternately with the milk, beating gently until smooth after each addition.

Step 11: Whip the egg whites until stiff but not dry. Fold the whipped egg whites carefully into the cake mixture.

Step 12: Spoon into the prepared baking pan. Bake for approximately 1-3/4 hours. Check for doneness and bake more if needed.

Step 13: Allow cake to rest for 20 minutes before removing from pan, then cool on rack.

Step 14: Dust with confectioners’ sugar and serve with ice cream or cinnamon whipped cream.
