Lemon Pine Nut Biscotti

Ingredients

• 1 3/4 cups all purpose flour
• 1/2 teaspoon baking powder
• Scant 1/2 teaspoon salt
• 1 cup sugar
• 2 eggs plus 1 egg yolk
• 1/2 teaspoon vanilla
• 1 tablespoon lemon juice from about 1/2 lemon
• 2 packed teaspoons lemon zest from about 1 large lemon
• 1/2 cup pine nuts

Directions

1. Set your oven rack in the middle position, then heat the oven to 350 degrees F. Cover a baking sheet with parchment paper. In a medium bowl, stir together the flour, baking powder, and salt, then keep it nearby.
2. In a large bowl, whisk the sugar, eggs, and egg yolk with some energy until the mixture turns pale and creamy, about 5 minutes. Mix in the vanilla, lemon juice, and zest. Tip in the dry mixture and stir until the dough comes together, then fold in the pine nuts.
3. Dust your hands with flour, because this dough will be sticky, and shape it into one log that is 4- by 12-inch long. Bake it until it is lightly golden and just beginning to dry out, about 25 minutes. Turn the oven down to 275 degrees F.
4. Once the log is cool enough to handle, take a serrated knife and slice it on the diagonal into cookies 1 1/2-inches wide. Arrange the pieces cut side down on the baking sheet, then return them to the oven until they are toasted and dry, 15-20 minutes more.
