I used this sauce on my Blueberry Baked French Toast. It would also be great on ice cream. It's very easy to make!!adapted from mybakingaddiction.com
2 cups fresh or frozen blueberries
1/2 cup water
1/2 cup sugar
2 TBSPs lemon juice
2 TBSPs cornstarch, mixed with 2 TBSPs cold water
1/2 teaspoon vanilla extract
1. 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.
2. In a small bowl, mix the cornstarch with 2 tablespoons of cold water.
3. Slowly stir the corn starch into the blueberries, taking care not to crush the blueberries. Simmer until the homemade blueberry sauce is thick enough to coat the back of a metal spoon, about 5 minutes.
4. Remove from heat and gently stir in vanilla.
Notes: You can adjust the sweetness of the sauce by decreasing or increasing the sugar. Also, if you want it to be more syrupy instead of thick, then add a little more water.
