Stir the “milk” and bring to a boil slowly on low heat. Cool to room temperature. Set the curd using the chosen starter on the first occasion and thereafter the best starter is a spoonful of this curd. The starter can also be stored in the freezer for up to 3 months.
Note
Try making a small amount first, since yoghurt can be a bit unpredictable the first few times. With the chilli tops, you may need to reserve some of the batch and use again with a fresh batch and more chilli tops, until you get a firm set yoghurt, which can be used as a starter for further batches. A starter portion of yoghurt or a starter culture normally gives reliable results.
