Prep the fruit by rinsing, removing any stems, seeds, or cores and, if needed, removing the skin. I removed the skins of the plums, which was more a choice about what kind of final texture I wanted rather than needing to remove them (like you would for something like mango).

Blend the fruit well. Then stir in the chia seeds. Cover and allow to thicken in the refrigerator for 1 hour, stirring once halfway through to make sure no big clumps form. That’s it!
