A friend of mine introduced me to a super simple way to make coconut yoghurt. I tried it out and it works a treat! There's no heating involved all you need is a cozy spot to keep it warm enough to culture. If you've got a yoghurt maker or a dehydrator, that will do the job but if not see below for some ideas.
All you need to make it is some store bought coconut yoghurt and a can of coconut cream. The store bought stuff acts as the 'starter' and contains the right bacteria to get it going. Just make sure your store bought yoghurt contains live cultures (check the ingredients list). Two great brands here on the Sunshine Coast are Coyo and Born Cultured.
Once you've made your initial batch you can use some of that yogurt to start the process again. You can repeat this method up to 3-4 times or until you notice a drop off in quality of the finished yoghurt i.e. less thick and tangy. Then you will need to buy another batch of store bought yoghurt to start the process again.
The type of coconut cream you use will determine the thickness of your yoghurt. You can also use coconut milk but it won't be as thick. Experiment with a few different brands to see what you prefer.
How to culture your yoghurt
Place in an esky filled with enough water to cover 3/4 of the jar. Close the lid and top up with more hot water if needed. This was the method I used. I left it to culture for about 18 hours and the water was still luke warm by the end.
Preheat your oven to its lowest temperature. Turn it off then place your jar inside with the door closed.
Wrap your yoghurt jar in a towel/blanket and place in a cooler bag with a hot water bottle or heat pack
If the temperature is warm enough (i.e. middle of Summer) wrap your jar in a towel and leave it in the warmest spot in your house
Place in the dehydrator set to 40 degrees
