My local supermarket has been selling cream at a very good price (19p for a large 600ml tub) as it is near its sell by date so I have been making butter like mad

The trouble is, now I have litres of buttermilk to use up...I have made scones, enjoyed the occasional banana milkshake, made pancakes and had wonderful yorkshire puddings and still I have jugs full of the stuff.
I was wondering if it is possible to use buttermilk to make yogurt...has anyone tried it? Or is there any reason not to give it a go? I make yoghurt with semi-skimmed milk all the time but if I can use the buttermilk it would certainly solve my buttermilk lake problem

Thanks!
