I've been told that I can make my own yogurt by boiling some milk, cooling it to blood heat, popping it in a thermos with some fresh yogurt, closing and leaving for 24 hours.
Then I can carry on making my own by keeping a little from each batch to make the next lot.
Anyone done it?
Any risks?
Safe for a toddler?
Full fat milk?
How much 'starter' yogurt?
Anything else you'd like to tell me? (It doesn't have to be yogurt related, I suppose).
