A few other follow ups -

Can you use more than one baking tray?

Are liquid eggs (in a carton, from Costco) legal?

In QT's run, she uses pam spray for nonstick, but I don't think that their use is explicitly permitted in the rules. Can the use of nonstick spray be added?

Some clarification should be had for the use of fridge/freezer. It's unclear if they can be used afterwards to cool the cookies down, which would give a structural advantage to frozen cookies.

Thanks!
