Add the cornmeal to a kitchen bowl with a cup of water. Whisk until smooth and watery, making sure there are no lumps. Set aside.
Add the coconut milk, cinnamon, and salt to a saucepan over medium heat, and bring to a boil.
Pour the cornmeal mixture into the boiling coconut milk, whisking continuously to prevent lumps. Keep whisking as the porridge thickens. (If the porridge is too thick for your liking, add more coconut milk a little at a time whilst whisking)
Add the remaining ingredients, turn the heat to medium-low, cover the pot and let the porridge cook for about 15 minutes.
Sweeten to taste with the sugar and serve.
