If using fresh blueberries clean the blueberries. If using frozen, thawed completely before putting in the blender.
Add 1/8 cup of water.
Blend until desire texture.
NOTE: You can use frozen or fresh blueberries. If using frozen, thawed them before putting in the blender. Also, frozen blueberries contain more water, you may have to adjust water. I usually starts with 1 tablespoon and go from there.
