1 tablespoon lemon juice

2 teaspoons cornstarch

2 cups blueberries

1/3 cup sugar

2 tablespoons water

1/4 teaspoon salt

In small bowl, combine the lemon juice and cornstarch.

In a medium saucepan, combine the blueberries, sugar, water and salt. Bring mixture to a boil over high heat. Reduce to a simmer and stir in lemon juice-cornstarch mixture. Simmer, stirring, until the sauce thickens slightly, about 2 minutes more.
