I refrigerated the unappealing colored yogourt and then today had a taste. Well, with some stevia and a couple of drops of vanilla, the resulting flavour was well, how should I put it? Tolerable, yes, that's the right word. I'm sure if I put real sugar in, it would taste better but that would defeat my purpose in making home made yogourt and getting all the probiotics to keep my tummy happy. I warned you, it is most unappealing looking but yes, tolerable.
