Orange Caramel Fudge

2 cups dark brown sugar
1/2 cup heavy cream
1/2 teaspoon baking soda
1 teaspoon butter
2 tablespoons grated orange peel
1/4 pound mixed nuts coarsely chopped (about 1 cup)

In a saucepan dissolve the sugar with the cream and baking soda over medium heat, stirring constantly. Bring mixture to a boil and stop stirring. Continue to boil the mixture until it makes a thick syrup that forms a ball when dropped into cold water (firm ball stage).

Remove the pan from the heat and add the butter, orange peel, nuts and a pinch of salt.. Beat the mixture well until it becomes quite thick.

Pour fudge onto a buttered plate and when cold cut it into 1-inch squares. or drop teaspoons of the fudge on to a large buttered platter.
