Just have to remember you’re talking in Fahrenheit. So in new money, heat to 90, cool to 52. In terms of the keeping it warm stage, do you think it’d work to put it in our airing cupboard? It seems to be about mid-20s C in there.
I get raw milk from these guys http://www.hookandson.co.uk/
They also do yogurt – it’s extraordinarily expensive, so perhaps it’d be a good investment for a stable starter. Hopefully. Better than just your supermarket Yeo Valley.
Will get some Friday and experiment at the weekend.
