1 1/2  ounces        semisweet chocolate
                  2 1/2  ounces        unsweetened chocolate
                  8      tablespoons   unsalted butter     {1 stick}
                  1      cup           sugar
                  3      large         eggs
                  7      tablespoons   all-purpose flour
                    1/2  cup           chopped walnuts
                  2      tablespoons   chopped walnuts

               1. Preheat oven to 325 degrees. Lightly grease an 8-inch square
               pan with butter or vegetable oil.

               2. Melt both chocolates and the butter in the top of a double
               boiler placed over simmering water. Cool the mixture for 5
               minutes.

               3. Place the sugar in a medium-size mixing bowl and pour in the
               chocolate mixture. Using an electric mixer on medium speed, mix
               until blended, about 25 seconds. Scrape the bowl with a rubber
               spatula.

               4. With the mixer on medium-low speed, add the eggs one at a
               time, blending after each addition until the yolk is broken and
               dispersed, about 10 seconds.  Scrape the bowl after the last egg
               and blend until velvety, about 15 seconds more.

               5. Add the flour on low speed and mix for 20 seconds; finish the
               mixing by hand, being  certain to mix any flour at the bottom of
               the bowl. Stir in 1/2 cup of the nuts.

               6. Spread the batter evenly in the prepared pan and sprinkle the
               remaining 2 tablespoons nuts over the top.

               7. Bake the brownies on the center oven rack for 25 minutes, or
               until toothpick inserted in center comes out clean. Allow the
               brownies to cool for 1 hour before cutting.

               Makes 9-12 brownies.
