The organization of Metlife is disgusting and sends people in circles. There is no definitive number to contact them...there are a hundred and you will get all the wrong ones unless you check back with the original employer to what contact number they may have.
To prep blackberries for making a puree: Heat the blackberries, fresh or thawed, in a saucepan over medium heat. Add 1 teaspoon of sugar and 1 teaspoon of lemon juice for every 1 cup of berries, fresh or thawed. Heat to warm the berries through, stirring as needed. Blackberry puree can be made with or without seeds. One cup of fresh blackberries produces 1/2 cup of puree, while 1 cup of thawed berries produce 3/4 cup of puree. Store the puree, seeded or seedless, in an airtight container or jar in the fridge for three to five days.
Directions: In a saucepan over medium heat, combine the blueberries, 1/2 cup of water, sugar and lemon juice. Stir frequently, and bring to a low boil. In a small bowl, mix the cornstarch with 2 tablespoons of cold water. Slowly stir the cornstarch into the blueberries, taking care not to crush the blueberries.
