End of summer is the time to gather fresh blackberries and this is such a great way to use up this bountiful fruit. Feel free to add many more blackberries to your yoghurt.
However tempting, resist the urge to remove the lid and check on the yoghurt, this will have a potentially negative effect on the end result. We set the yoghurt on to incubate last thing at night.
By adding the dried milk, this makes the yoghurt creamier.
Do not add anything to the yoghurt before or during incubating such as sugar and fruit, this should all be done afterwards. Yoghurt should last about 4 days in a sealed container in the fridge.
