I noticed that King Arthur has on backorder until 3-31 a biscotti pan Item
5128 ($19.95) size 12 x5-1/2 x2.
It occurred to me that I could use a glass pyrex baking dish 12 x 7 x 2 for
this same purpose.

I suppose there is a science to the size of this pan being 5-1/2 vs. my 7;
perhaps that is the size that biscottis should be formed into. I'm thinking
of maybe putting a 1-1/2 strip of aluminum foil to take up the 1-1/2" space.
Any other ideas for something else besides aluminum foil, or would one just
go for the larger size biscuit?
Any comments, please.
Thanks.
