Greek yogurt made with yogurt culture.
Tried and tested by our Shop Manager Andre Kruger
Firstly sanitize all the equipment you'll be using. (http://www.cheeselab.co.za/collections/ingredients/products/iodophor)
Pour the milk (combine with milk powder if using) in a pot and slowly heat to 84 degrees Celsius and then let it cool down slowly to 46 degrees Celsius.
Ensure you keep your thermometer your sanitizer solution to prevent possible contamination when taking temperature readings..
Once your milk has cooled down to 46 degrees you can gently whisk in about a quarter of a teaspoon of yogurt culture (about 1ml) and then cover the container.
The temperature has to be maintained at 46 degrees for at least 6 hours , so a hot-box or wonderbag is a wonderful accessory to have for this purpose , but you could alternatively wrap the container in a blanket.
