One of the small changes I have made this year (well, really in December of last year) is to make our own yoghurt. I picked up a yoghurt maker at Aldi in the middle of last year for $15 (I am still bitter that it dropped to $9 when on clearance - but you win some, lose some) with the intention of making yoghurt but wasn't keen on using the pre-mixed sachets as I like to know what is in my food!
A bit of research yielded Which Name?'s recipe. Which, I like a lot. This is my fourth batch and three have been a success. We won't talk about the fourth - as I still don't know what went wrong.
The process for me is simplified because of my yoghurt maker which means once the yoghurt starter has been stirred in I just transfer the liquid to the yoghurt maker and let it do its thing. I do have to refill the boiling water after 12 hours and give the process another 12 hours to get my desired consistency.So planning in advance is essential - do not wait until the yoghurt pot is empty to make your next batch; or people have a tendency to eat your starter yoghurt in the meantime:)
I figure this change is saving us money and a lot of packaging! Besides, homemade yoghurt is so yummy in the morning with homemade granola - though that is a post for another day.
