Unsalted butter for greasing baking sheet
All purpose flour for dusting baking sheet and work surface
2 cups all purpose flour
2 cups corn flour or very finely ground cornmeal
2/3 cup sugar
2 1/2 tsps cream of tartar
1 tsp baking soda
1 tbsp anise seed, or to taste
5 tbsp unsalted butter, melted
3 tbsp olive oil
1/4 cup milk
1/4 cup sweet white wine
Preheat oven to 375F degrees. Grease baking sheet with softened butter and dust with flour, shaking off the excess. Set aside.
In a large bowl, combine the flour, corn flour, sugar, cream of tartar, baking soda, and aniseed. Add the melted butter, olive oil, milk and wine. Stir to mix well.
In a small bowl, beat the eggs lightly, then set aside 1 teaspoon for glazing. Add the remaining egg to the flour mixture and stir ingredients together thoroughly. Turn the mixture out onto a lightly floured work surface and knead until the dough holds together in a compact mound, about 5 minutes.
Plunge both thumbs into the center of the mound and pull the dough into a thick ring about 8 inches in diameter. Center the doough ring on the prepared baking sheet and brush the top and sides with the reserved beaten egg.
Bake until golden brown and a wooden skewer inserted into the cake comes out clean, about 30 minutes.
Transfer to a wire rack to cool completely. (The flavor of the cake improves on the second or third day after baking. Tightly wrapped and refrigerated, it keeps for a week.) Cut into slices to serve.
Makes 8 to 10 servings.
