the fresh blueberry sauce

I wanted to keep the freshness of the blueberries. To do this, I divided the blueberries and used 1/3 of them for making the sauce. The blueberry sauce takes only about three minutes to cook. Once the sauce is ready, stir in the remaining fresh blueberries, and the topping is prepared.

Key Lime Pie Version

To make this gluten-free key lime dessert into a pie, follow the same directions except using a deep dish-style pie plate.  You may have to adjust the baking time probably by about 3 – 5 minutes longer. The gluten-free key lime pie comes out spectacular!
