Hi thanks for your replies.
I am absolutely sure I followed the receipe. The only thing that is not accurate is the amount of culture as it came in a pre measured pack.
The rennett is tablet form, not sure of make, but is stored in the pantry.
I am really quick to pick up mastitis as the milk get really salty when that occurs and as we are drinking it raw, would be picked up straight away. I also hand milk and am a vet nurse so hopefully Ive got that base covered, but I will try the pH.
Interestingly enough I threw another rennett tablet in making it twice the strength after nothing happened left it over night, I now have curds, not fantastic but formed, so ill press it and see. Will the cheese be any good, who knows. will keep you posted
