I am just starting the SCD diet and am interested in making the yogurt. I would like to buy a yogurt maker but there are so many types I am confused as to which to buy. I know it says in the SCD yogurt making instructions ferment the yogurt for 24 hours, yet it looks like many online only do 6-8 hours or so. I don't want to spend a ton as I am not sure this will work out, but don't really have the time to do the other methods (heating pad, etc.). Any suggestions on a yogurt maker that is easy to use, not terribly expensive (maybe $40 give or take?) and works well? Any help/guidance is appreciated!
