3 3/4 c. sifted powdered sugar
1/2 c. unsweetened cocoa powder
1/2 c. butter
1/4 c. evaporated milk
1 tsp. orange peel
1/2 c. chopped walnuts

Line an 8 x 4 x 3 inch loaf pan with foil so it extends over edges of pan. Butter the foil; set pan aside. Sift the powdered sugar and cocoa into a bowl. Set aside. In a small saucepan, combine butter, milk, and orange peel. Cook over medium heat just until boiling, stirring constantly, until butter is melted. Remove from heat; cool slightly. Stir into powdered sugar mixture. Add walnuts, stirring until well combined. Spread fudge in prepared pan. While fudge is warm, score at 1 inch intervals. Chill in the refrigerator for several hours or until firm. When firm, use foil to lift fudge out of pan. Cut into pieces.
