When I was reading Jonas' thread about cross stacking ( http://www.pizzamaking.com/forum/index.php?topic=36721.0
) I came across these little legs to stack pans called "Sklips." I have been thinking of buying them but small quantities are expensive because of shipping.
The whole subject got me thinking about the frustration I sometimes have when I want to proof something in the fridge in a 1/2 sheet pan ( the approx. 13 X 17 pans) - be it focaccia, Sicilian pie, bagels, whatever. You have to fuss with plastic wrap, which never fits right without multiple pieces, and spray some Pam around. Further, if I have more than one pan, it really does become a battle for fridge space.
In my "googling" around, I found a simple fix that I was not previously aware of - Plastic Sheet Pan Lids. They seem perfect for proofing and you can stack pans. My narrow shelf in the fridge is about 6 inches and these - both pan and lid - take 2 inches in height. So, I can easily stack two in my space and avoid the battle, the wrap and the Pam.
$5 each in the local restaurant supply store!
