1. Prepare all materials
2. Put blueberries into the bucket of the bread machine
3. Add cornstarch and soft white sugar to the water and stir well
4. Pour the blended flour into the bread machine bucket, just submerging the blueberries, put the bread machine bucket into the bread machine, install it, cover the bread machine cover, and start the fancy jam function of the bread machine (I use Bai Cui Bread machine), when the buzzer is heard, the jam is made (about 1 hour and 20 minutes). After taking it out, put it into the glassware that has been blanched and dried before cooling, then seal it, and store it in the refrigerator.
