Wash 2 bottles of jar. Heat the jars in the oven for 5 minutes. This will kill the bacteria inside.
While still hot, pour in the jam into the jar. Close the lid. Turn the bottle upside down. This will kill the bacteria under the lid. The jam can be preserved longer.
After 5 minutes, turn the bottle to normal position.

Notes
Important note:The coconut milk should be very pure. Please ask the seller to press the coconut shreds without adding any water at all. Always sieve the curd after steaming. This will create a very smooth texture.Always use a clean utensil to take out the jam from the container. Never use the same utensil after it touches bread or cake. This way your jam can be kept longer. Always keep the jam in the chiller, especially after opening.
