When we first got it, I used one Easiyo sachet to make one container of yogurt. From then on, I've used 1 heaped tablespoon of the last batch of yogurt and then just milk powder. My steps: - Mix ~500ml tap water with 150g of milk powder (just put the lid on and shake vigorously, I always put the water in first as the mixing is much easier). - Add 1 heaped tablespoon of existing yogurt (the previous batch, or I've used Chobani successfully (I've heard some commercial yogurts work and some don't)). - Fill (leave 5mm gap at the top) the container with tap water. - Shake again to mix (less vigorously). - Add boiling water to maker. - Put jar in. - Generally I try to wait 12 hours, sometimes up to 18 when I'm not home. - Refrigerate and enjoy :-) I enjoy the yogurt straight, but I wouldn't expect everyone to (it may not be sweet enough) - my wife adds honey or jam and fruit when serving. (I now actually freeze one tablespoon of yogurt as soon as a batch is done, and use it for the next batch after thawing in the fridge (overnight).)
