Instructions
Making the Blueberry Sauce
Place the freeze-dried blueberries in a resealable bag and use a rolling pin to crush the berries into a fine powder.
Add the frozen wild blueberries, tapioca flour, sugar, freeze-dried blueberry powder, lemon zest, and lemon juice into a medium saucepan. If you are using cornstarch instead of tapioca flour, place the cornstarch in a small bowl, add a small amount of water and stir to create a slurry. Then pour the slurry into the saucepan. Cornstarch has a tendency to stay in clumps if added to the mixture and it doesn’t taste good to bite into a clump of cornstarch.
Cook over medium heat until the berries have thawed. This should happen within a couple minutes since they are so little. Use a potato masher or your spatula to smash the blueberries while cooking. This will help to release the moisture from the berries to create a sauce. Continue cooking while stirring occasionally until the mixture begins to boil and thickens slightly. This should take approximately 5 minutes.
Remove the pan from the heat and transfer the mixture to a bowl to allow it to cool. If you want the blueberry sauce to cool quickly, pour the mixture onto a baking sheet and spread it into a thin layer. Cool until it reaches room temperature. The sauce will continue to thicken while it cools.
Storing the Blueberry Sauce
Store the blueberry sauce in an airtight container in the fridge up to 5 days. You can also store it in the freezer for up to 3 months. Keep in mind that some storage containers can be stained by the blueberry sauce while in the fridge/freezer. Plastic tends to stain more than other containers. Thaw the sauce to room temperature before serving.
Serving Blueberry Sauce
Looking for ways to use blueberry sauce? I love spooning it over a slice of cheesecake or a scoop of vanilla ice cream. You can also use it to fill lemon cupcakes for a tasty spring and summer dessert.
