used 10 cubes and only a small amount of red rasb. since they were not abundant in our garden, replaced with 1 cup of blackberries. Not great, not bad, strong banana flavor, purple color. 7/10 probably better with red rasb. tried another rasberry smoothie recipe from another site with 1cp rasb. 1 cup of starwberries, 1/2 cup pineapple juice and ice, i threw a few blueberries in and it was quite good.
