I bought this kit knowing he would not be home in my yogurt. So I make my yogurt. Then yaouts 2 + 1 yogurt pot filled with milk + 2 tablespoon of syrup = 3 yaouts to drink after 2 hours in the fridge. Very easy to clean with the brush. No plastic taste. The amount used to have in the fridge all the time. No leakage even if the liquid is put in place of the yogurt.
