Toll House® Famous Fudge Recipe !!!

INSTRUCTIONS
Things first, get all the ingredients ready. Then prepare the form, I normally pick a small, around 9 inches, form and cover it with foil.
Put sugar, butter, salt, and condensed milk into the medium-sized pot. Put the pot on the fire and make it boil while constantly stirring it. Boil it for 4 minutes, remember to occasionally stir it a little, the mass has to become smooth and indiscreet. Sugar must dissolve fully.
Take the pot off the fire and add marshmallows, nuts, chocolate morsels, and vanilla extract. Mix the mass until marshmallow dissolves.
Put the hot dessert into the form and put it into the fridge to cool down. The fudge should cool in the fridge for two hours, after that take it out and cut it into pieces.
