Okay, from your description, I think I am getting it the right texture, as it is "mushable" not, crumbly.
I think I will try a batch with citric acid to see if the whey comes out clearer. I don't think it is the cheesecloth, as it is the same as I use for cream cheese and the whey from that isn't white. I just didn't want to add too much vinegar and end up with grainy mascarpone.
BTW, I still have the whey sitting in a jar (waiting to be fed to the chickens) and there is now a clear, yellow-green layer at the bottom and the top is quite thick, so I'm going to ladle it off and see what it tastes like.
