You can save one or two tablespoons of your finished homemade yogurt to use in your subsequent batch of dairy-free yogurt once you have finished making one batch. For each 15-ounce can of coconut milk, whisk in 1 spoonful of plain yogurt to replace the powdered starter.
Incubate the coconut milk yogurt for 24 hours for a creamy, tangy result. Set the incubation time between 8 and 12 hours for thinner and less tart yogurt.
After the yogurt has chilled for eight hours, I usually add one tablespoon of maple syrup and 1/2 teaspoon of vanilla extract to sweeten it.
