Having a great time with this thread, and can't wait to see the outcome. This pizza looks great.
In response to post 142 about the cheddar.
You see Formost coop signs in front of many dairy farms here in WI. I believe they are a rather large outfit. Not sure how easy it is to get product from them.
Wisconsin IS the dairy state with many other excellent cheese businesses.

They make an excellent whole milk Mozzarella (which is available direct only), and, the other cheeses that are available through the local grocers like Pick n Save or Woodmanns Market are really good, Plus, their prices are reasonable.
They are super nice on the phone and will ship you whatever you order same day. I've had excellent experiences with them and I'll bet they can supply you with the cheddar you're looking for. As I said their Mozzarella is excellent!
Give them a try!
