Let the berries sit out at room temperature for 5 minutes.

Add the berries, bananas, and juice to a high speed blender or food processor. If using a blender, start blending on low. Slowly increase the speed until all of the fruit is pureed. Continue to blend 1-2 minutes until smooth and creamy, stopping to scrape down the edge of the container as needed. Add maple syrup as a sweetener, if desired.

Transfer to a container and press plastic wrap over the top of the sorbet, it should touch the sorbet directly to omit air and prevent the sorbet from being icy. Place a lid on the container and freeze overnight.

Let sit out at room temperature before scooping.
