Half-fill your yogurt jar with room temperature, drinking water. Add the contents of a yogurt sachet, pop on the lid and give it a good shake. Fill the jar up with more water to about 5mm from the top... and shake again.

Push the plastic insert spacer down inside the Yogurt Maker as far as it can go. (Check the correct side is facing up). Pour boiling water into the Yogurt Maker to the top of the plastic insert spacer.

Put your jar into the Yogurt Maker so that it sits on top of the plastic insert. The boiling water will rise part-way up the sides of the jar. Put the Yogurt Maker lid on and leave it on your kitchen worktop for 8 to 12 hours (or overnight) to let the yogurt set... and the magic will happen!
