Place the corn starch in a small cup and add a little of coconut milk and mix with a spoon until it dissolves.
Add all the ingredients to a medium pot over high heat and add the corn starch mix. Stir until the sugar is dissolved. Bring to a boil.
Once it boils, lower the heat and let it simmer for 20 minutes. Stir occasionally.
Once it's done, take it off the heat and pour the mixture into 4 small bowls. Let them cool on the counter. When they are no longer warm to the touch, refrigerate them.
Notes
When I refer to coconut milk it is the one that comes in the half gallon, and not the can
Get the unsweetened, unflavored kind
This recipe makes a lightly sweetened rice pudding. If you like it sweeter add more sugar to taste.
