Looks like I have only posted the Pound Cake Recipe here:

I tried the "Easy Blueberry Sauce Recipe" from Taste of Home:
Ingredients:
1/4 cup sugar
1 teaspoon cornstarch
Dash salt
1/4 cup water
1 cup fresh or frozen blueberries
1-1/2 teaspoons of lemon juice
1/2 teaspoon grated lemon peel
Directions:
In a small saucepan, combine the sugar, cornstarch and salt. Gradually whisk in the water until smooth. Add the blueberries, lemon juice and lemon peel; bring to a boil over medium heat, stirring constantly. Cook 2-3 minutes or longer or until thickened, stirring occasionally. Serve warm or chilled over ice cream, angel food cake or pound cake.
Changes I used:
I doubled the amount of blueberries, sugar and cornstarch but all else by the recipe. It turned out a little too sugary sweet - next time will just double the blueberries.
I used frozen blueberries - no need to thaw, just rinsed to get ice crystals off them. And chilled it in fridge before using.
