Add all the ingredients to the Thermomix bowl and cook for 4 mins/100°C/reverse/soft speed, without the measuring cup. Place the simmering basket on top of the Thermomix lid to prevent splatter.
Taste and add a little more maple syrup if you prefer a sweeter compote. The compote will thicken as it cools.
Notes
Frozen blueberries: These work just as well as fresh. There is no need to defrost them first, simply add them straight to the Thermomix bowl and cook as directed. The compote may be slightly juicier but will thicken as it cools.Storage: Store the compote in an airtight container in the fridge for up to 5 days. It also freezes well.
