(rolling boil) Mix together in a large bowl; 3 packages chocolate chips, 7 oz. jar marshmallow cream, 1/2 lb. melted margarine. Cream margarine and marshmallow together and add chocolate chips. Pour hot mixture over chocolate mixture. After chocolate has melted, add 2 cups of nuts and 1 tsp. of vanilla, blend well, pour into buttered pans and chill in refrigerator.

HISTORICAL NOTE: Given to Amy DeVore by Emma Julian c. 1930, this is "supposedly" the original recipe for Sees Fudge, produced by the Sees Candy Company, Los Angeles. Emma allegedly worked for Sees and later owned her own candy store.
