Note: If you are using frozen raspberries, allow them to thaw slightly.
Place raspberries, coconut milk, sugar, and lemon juice in a blender. Puree until smooth.
Pour the raspberry sherbet mixture into your ice cream maker bowl and follow the instructions according to your ice cream maker. Most sherbets are done anywhere between 20-35 minutes. Watch it until it reaches the consistently you prefer, and then turn the ice cream maker off.
Scoop into bowls and serve. Or, transfer the sherbet to a freezer-safe airtight container and freeze.
