Valentine Brownies (Ellen Patton got this recipe from a chocolate class taught by June Jacobs)
Makes 24 squares (or about 18 hearts) in a jelly roll pan - these will be large!

Preheat oven to 350 degrees.  Melt 6 ounces unsweetened chocolate and 3/4 cup unsalted butter in a double boiler over simmering water.  Set aside.  Meanwhile, mix 3 cups sugar and 6 extra large eggs in a large bowl with a wooden spoon.  Add 2 teaspoons vanilla and a pinch of salt.  Add the chocolate mixture.  Now stir in 1½ cups unbleached flour and 1½ cups chopped walnuts.   Pour into well greased big square pan (or jelly roll pan).  Bake for 25 minutes.  Cool and cut out with a heart-shaped cookie cutter.
