Blender Tips
Load in liquids first.
Add the ingredients in the right order, starting from the lightest and ending with the heaviest. This means you’ll need to add liquids first, followed by seeds and powders, fresh fruits and vegetables, and frozen fruit, in that order.
Use a blender tamper.
Using a blender tamper will ensure all of the ingredients are blended properly. If the blender lid is on, the tamper won’t touch the blades.
Cut fruit into chunks.
When making a smoothie, it’s important to use chopped fruit. This will make it easier for the blender to break up. If you have a powerful blender, you can use larger pieces. If you have a less powerful blender, use smaller pieces.
Start on low, then increase to high.
To the keep the motor cool, avoid blending on low the whole time. Start on low then increase to high speed.

Expert Tips
- For a less sweet smoothie, omit the Medjool date.
- If the smoothie is too thick for your liking, add a bit of milk and blend for 10 seconds.
- Cut the Medjool date into pieces if your blender is not powerful. This will prevent chunks of date in your smoothie.
- Smoothies are best when they’re enjoyed immediately. If you need to store leftover smoothie, keep it in an airtight glass container in the refrigerator for 1-2 days.
