All three hard cheeses I’ve made so far have had plain yoghurt as the starter, basically because I didn’t have any ‘real’ starters and couldn’t wait for them to arrive. I’ve only tasted one, a month after pressing, and it was a bit salty, but definitely cheese. I’m leaving it to age a bit longer. For the second one I cultured a carton of cream with yoghurt, and used that as my starter. Haven’t tasted it yet (won’t be ready until next month), but it smells heavenly, very buttery. I wait in high hopes!
I also look forward to the day when I will be able to make cheeses actually deserving of a name…..
