Creamsicle Sorbet

1 Arrange the clementine segments in a single layer on a parchment-lined tray.
2 Freeze for at least 4 hours, or until completely frozen.
3 Add the frozen clementines to a high-powered blender or food processor and pulse several times to break them into small pieces.
4 Add the kefir and maple syrup.
5 Blend until smooth, thick, and creamy, scraping down the sides as needed.
6 Taste and add additional maple syrup if desired.
7 Serve immediately for a soft-serve texture or freeze for 30–60 minutes for a firmer sorbet.
