2/3 c  Unsalted butter

      2 oz Unsweetened chocolate

           - cut into small pieces
      2 oz Semisweet chocolate

           - cut into small pieces
      1 c  Granulated sugar

    3/4 c  Light brown sugar, packed

      3    Jumbo eggs

  1 1/2 c  Sifted all-purpose flour

    1/2 ts Salt

      2 ts Vanilla

  1 1/2 c  Coarsely chopped walnuts

           - OR pecans
  PREHEAT THE OVEN TO 375F. Melt the butter with the four squares of
  chocolate in a large saucepan over low heat, stirring often. Remove the pan
  from the heat and mix in the granulated and brown sugars, eggs (one at a
  time), flour, salt, vanilla and nuts. Spread the batter into a
  well-buttered 9-by-9-by-2-inch baking pan, pushing it well into the corners
  and smoothing the top. Bake the brownies uncovered for 35 to 40 minutes, or
  until the brownies feel fairly firm and begin to pull away from the sides
  of the pan. Cool the brownies in the upright pan on a wire rack for at
  least 30 minutes. Cut them into large squares.
