Preheat oven to 375°.
In a mixer, cream together butter and sugar. Add in eggs one at a time and mix until thoroughly combined. Mix in anisette and vanilla.
In a separate bowl, whisk together cornmeal, baking powder, salt, anise seed and flour. Add to egg mixture to form dough. Carefully mix in chopped almonds.
Remove dough from mixer and divide into 6 even amounts (or 3 if you want to make bigger biscotti).
Roll each piece of dough into a log about 12 inches long and place on parchment-lined baking sheets, making sure there is plenty of space in between (I use 2 baking sheets for 6 logs, 3 on each one). Flatten logs slightly and brush entire surface with egg wash using a pastry brush. Sprinkle the tops with granulated sugar.
Bake logs for 15-20 minutes (depending on size) until golden brown and firm but be careful not to overbake.
Turn oven down to 275°.
Cool biscotti logs slightly and then cut crosswise into ½-inch wide biscotti on a cutting board. Transfer back to baking sheets and bake a second time in single layers for 10-15 minutes longer just to lightly toast. Cool completely.
