Orange-Cranberry-Pistachio Biscotti

Preheat an oven to 350°F. Line a sheet pan with parchment paper.

Put the cranberries in a small bowl and cover with Grand Marnier liqueur. Soak until plumped, about 15 minutes. Drain, pat dry and set aside.

In a large bowl, combine the flour, yellow cornmeal, baking powder, and salt and whisk to mix well. In another bowl, use a fork or your fingers to rub the orange zest into the sugar.

In the bowl of a stand mixer fitted with a paddle attachment beat the orange sugar and butter until light and creamy. Beat in the eggs until well blended, about 2 minutes. Add the vanilla extract. Gradually stir in the flour mixture and beat until smooth, about 3 minutes. Stir in the cranberries and the whole pistachios.

Divide the dough in two and shape into two logs about 1 1/2 inch high onto the prepared sheet pan. Bake for 15 minutes until just turning golden brown. Let cool for about 15 minutes.

When the logs are cool, transfer them to a cutting board and cut on the diagonal into slices about 3/4 inch thick. Put the slices, cut side down, on the baking sheet and return to the oven. Bake until the slices are lightly golden, about 6 minutes. Turn the slices over and bake until golden on the other side, 5 to 6 minutes more. Transfer the cookies to a wire rack and let cool.

In the top of a double boiler set over but not touching gently simmering water, melt the chocolate and butter. Remove from the heat. Put the finely chopped pistachios in a small bowl. Working quickly, dip one-third of each cookie into the chocolate and then dip the chocolate-covered tip into the pistachios. Return the cookie to the rack until the chocolate sets.

Store biscotti in an airtight container at room temperature for up to 1 week.
