I got the cheese ball made last night, and it's just your average sized cheese ball...probably 2-3 cups worth. I'll probably divide it in two.
I must say, It is outstanding! Depending how strong your cheese is (mine was nice and ripe), you might want to add another oz of cream cheese.
The only thing being, I couldn't find any chopped pistachios, so I shelled them all by hand. As I was sitting there doing that (for at least an hour...I have numb fingertips), thinking of how much trouble it was...I remembered watching grandma peel the grapes for her Waldorf Salad.
Anway, the pistachios are going to be perfect. The cheese ball itself has a bit of a greenish cast from the mold in the cheese, and the green nuts will be perfect.
