Step 1

Wash blueberries and add to a small pan.

Step 2

Put the arrowroot power into a small bowl or cup and stir the orange juice in very gradually. Start with a tiny bit of orange juice and keep stirring to avoid lumps forming.

Step 3

Pour the orange juice mixture over the blueberries.

Step 4

Throw in all the other ingredients.

Step 5

Place over a medium heat and simmer, stirring frequently, until it starts to get nice and thick.

Step 6

The orange juice will gradually change from orange to purple as the blueberries break down.

Step 7

If you find it is getting too thick, add a tablespoon or two of extra water.

Step 8

Once the sauce is dark purple and thick and the blueberries have broken down remove from the heat. This should take between10 - 15 minutes.

Step 9

Either serve warm or let it cool.

Step 10

Will keep for about a week in a jar in the fridge. It also freezes well.
