Of course you can use fresh fruits. I tested it with frozen (thawed) berries and was pretty happy about the result. So there is the possibility to prepare them also in the winter season. Maybe with a little bit of cinnamon or so. Yum.
Green Smoothie
I like it really, really green. But in the winter season I add some frozen berries from time to time. For me everything green is allowed that my nose likes to smell and my instinct accepts. I easily find out what doesn’t work for me: I just cannot smell it while drinking. Chives doesn’t work even if I love fresh chives. I love to add some lime juice. If the Green Smoothie is my lunch I add a half of a can of coconut milk. The fat keeps me satisfied until dinner. I love it!
