BTW I'm pretty sure Mary's calculations are off just a bit.
The devil you say!
Actually, I wasn't thinking about the pot or the mold size, I was thinking about the draining/pre-draining. I have a VERY large colander that I got just for draining Stilton curds and it is a challenge (candidate for Understatement of the Year Award) to fit everything from a piddly 2-gallon make in there.
So no, my calculations are quite correct, thank you.
How are you going to handle the draining?
