Ingredients

1/2 cup heavy cream 

1/4 cup milk 

1 teaspoon cornstarch 

1 cup light-brown sugar 

2/3 cup light corn syrup 

4 tablespoons unsalted butter 

Preparation

In a small bowl, combine cream, milk, and cornstarch; set aside. In a medium saucepan, combine sugar, corn syrup, and butter. Cook over medium-high heat, stirring, until butter has melted and sugar has dissolved, 4 to 5 minutes.

Reduce heat to medium-low. Add milk mixture; bring to a boil. Boil 30 seconds; remove from heat. Cool slightly before serving, or store, covered, in the refrigerator up to 2 weeks. Before serving, reheat in a saucepan; thin, if necessary, by adding up to 2 tablespoons cream.
