Old Fashioned Fudge - cooking recipe

Ingredients

3 c. sugar
3/4 c. cocoa
1 c. evaporated milk
dash of salt
2 sticks margarine
1 tsp. vanilla flavoring

Preparation

Mix sugar, cocoa, salt and milk in pan (I use and it's best to use a black iron frypan).
Add stick margarine.
Cut margarine and cook over medium heat until candy thermometer reaches 240\u00b0.
If you don't have a thermometer, bring to a boil and boil for 3 1/2 to 4 minutes.
Remove from heat and add vanilla.
Beat until it begins to thicken.
Pour into 9 x 13-inch greased dish.
Cut into squares when hardened.
