2/3 c. (sm. can) undiluted carnation evaporated milk
1 2/3 c. sugar
1/2 tsp. salt
1 1/2 c. (about 16 med.) diced marshmallows
1 1/2 c. (1 1/2, 6 oz. pkg.) semi-sweet chocolate pieces
1 tsp. vanilla

Combine milk, sugar and salt in saucepan over medium heat. Bring to boil and cook 4-5 minutes, stirring constantly. (Start timing when mixture starts to "bubble" around edges of pan.) Remove from heat. Add marshmallows, chocolate and vanilla. Stir vigorously for 1 minute (or until marshmallows are melted and blended). Pour into 8 inch square buttered pan. Garnish with nuts if desired. Cool. Cut in squares. Makes about 2 pounds.
