Dan got me thinking about baking outside again so I did a quick Google and came across this video of someone baking bread in a big green "egg", which actually looks more like someone putting a hunk of drywall paste in a big green golf ball. I guess it doesn't even need any final proofing. I wonder why they don't show the finished product?
