The quality of the chocolate used will affect the flavor and texture of the fudge. Ghirardelli semisweet and unsweetened chocolate is best for this recipe. Don't make this fudge without the peanuts; they are crucial to the texture. Peanuts can be toasted or not. Store the fudge, tightly wrapped in plastic, in a cool place for up to 2 weeks or in the freezer for 3 months. If frozen, allow ample time to let it reach room temperature before cutting. Makes 2.5lbs. Ingredients and instructions for Rocky Road version.
