Here is a recipe I found for edible coal. Too late for this year, but maybe next year for my adult son... lol

Lump of Coal Candy

by Tami Rose

Do you know someone who has been naughty this year? Fill their stocking with these lumps of candy coal! This also makes a great gag gift!

What You Need

2 cups granulated sugar

3/4 cup light corn syrup

1/2 tsp. black paste food color

1/2 cup water

1 tsp. anise extract

What You Do

Line an 8-inch square baking pan with foil, extending edges over the sides of pan. Lightly grease foil with butter or baking spray.

Combine sugar, corn syrup and water in a heavy, non-stick, 2-quart saucepan. Stir over medium-low heat until sugar is dissolved and mixture comes to a boil. Cook about 15 minutes, without stirring, until a candy thermometer registers 290 degrees F.

Immediately remove from heat. Stir in anise extract and food coloring. Pour mixture into prepared pan. Cool completely.

Lift candy out of pan using foil. Place candy between 2 layers of heavy-duty foil. Using a hammer or mallet, break candy into pieces the size of a lump of coal.

Fill a plastic baggie with a few pieces of coal and attach the following poem:

POEM:

I heard you have been naughty not nice,

And Santa even checked his list twice.

So all the way from the cold North Pole

all you're getting is a bag of coal.
