First put your strawberry base into the blender then add your cherries and cranberry juice.
Next blend on lowest setting, slowly turning up settings till the second one. When it stops blending, (blade stops turning because something is blocking it) turn off immediately and mix around with rubber spatula. Before blending again turn back to lowest setting. Do this again until you are able to get to two without it stoping. Once you get to two, try to get to three. Do the same stoping and mixing and going up a level until you get to the center setting (if there is ten, this would be fifth). Keep on that (even if it still stops) and blend until smooth. Scoop into bowl and enjoy
