Chocolate Icing

This historical boiled icing relies on dissolving sugar in liquid and heating it to create a syrup that sets as it cools. The brown sugar provides molasses content which adds moisture and helps prevent crystallization. The fat from cream and butter creates emulsification, giving the icing a smooth, spreadable consistency rather than a brittle candy texture. Boiling the mixture concentrates the sugar solution and evaporates excess water, allowing it to thicken properly when cooled.
