Scottish Tablet - cooking recipe

Ingredients

1 (14 ounce) can sweetened condensed milk
1/2 cup water
1/2 cup light cream
2 pounds white sugar
1/4 cup unsalted butter
1/2 teaspoon vanilla extract

Preparation

Butter a 10x15 inch jellyroll pan, and set aside.
Pour milk, water, cream, and sugar into a large, heavy bottomed saucepan. Add the butter, and bring to a boil over medium-high heat, stirring constantly.
Reduce heat to medium, and cook for 20 minutes, stirring constantly. After 20 minutes, remove from heat, and beat in vanilla extract. Continue to stir until the mixture is no longer glossy. Pour into prepared pan, and let cool until hard, about 6 hours.
