Is it true that eventually, after several batches, you can't use your own homemade yogurt as a starter and need to use store-bought? I've noticed that my yogurt's been really thin lately... it's always been thin but I think it's been even thinner than usual lately. Could that be related? If I do need to use store-bought for a starter, is it OK to use Greek yogurt as a starter?
TIA for any replies.
