try adding 1/2 cup of dried milk, that helps. also make sure your starter is active (I use store bought live yogurt at first) and leave it out 12 hours instead of 8.I would like to make a thicker yogurt and have read where people use jello however I don't want flavoring. Has anyone added gelatine? and if so how much do you think? Or any ideas to thicken similar to store bought also how do you make your yogurt?
