Blueberry Sauce

Before getting started, rinse the blueberries and pat them dry with a few paper towels.* You can skip this step if using frozen berries.
Whisk the cornstarch and 1 tablespoon of water together to make your cornstarch solution.
Combine the other 1/3 cup of water, cornstarch solution, and sugar in a medium saucepan, whisking 'til the mixture is smooth and free of any lumps
Use a spatula to stir in the blueberries and lemon juice.
Place your suacepan over medium heat, stirring constantly as the mixture cooks. Continue to stir for about 5-6 minutes, or 'til the sauce thickens, and the blueberries release their juices, creating a syrupy consistency.
Remove your blueberry sauce from the heat, and allow it to cool down to room temperature on the counter.
That's it! You can serve it now on your favorite breakfasts and desserts, or you can store it in an airtight container or mason jar in the refrigerator or freezer until ready for use.
