Condensed milk may be used instead of fresh milk. It should have water added according to the directions on the can.
Marshmallows or marshmallow cream may be added to any fudge after it has been taken from the fire. One cup of marsh-mallow to two cups of sugar is a good proportion.
Flavoring may be varied to suit. Orange extract is good with brown sugar, chocolate or molasses. Lemon extract or lemon-juice is good in a white-sugar fudge from which the chocolate is omitted.
