Put the coconut milk and sugar into a heavy-based pan over a medium heat, and bring to the boil, whisking until the sugar has dissolved.

Step 2

As soon as the milk has reached boiling point, reduce the heat to its lowest setting.

Step 3

Simmer for an hour or so, stirring occasionally, until the milk has reduced by about half, and reached a thick consistency.

Step 4

Once it's reached your desired thickness, remove from the heat, and whisk once more.

Step 5

Pour into a sterilised glass jar, allow to cool a little, then put the lid on. Store in the 'fridge for up to a month.
