Depending on whether you use all frozen fruit or some fresh fruit, you may need more or less almond milk to blend. Adjust as needed.

If you prefer a sweeter smoothie, use a riper banana. If you prefer a less sweet smoothie, use a less ripe banana. (tip: I like to freeze a batch of bananas when they reach the level of ripeness that I prefer)

Always add liquids to your blender first, followed by seeds, then greens, then the fruit on top. This will allow the blender to blend more easily.
