After baking up a storm for the holidays, I noticed a pattern in regards
to cakes and cookies sticking to the pan.  In a large percent of the
cases, whenever I used a non-stick spray.....they stuck.  It seems that
Mazola spray was more of a problem than Pam [slightly].

When I used butter or Crisco....none stuck!  Even the first pizzelles
did not stick!

Neither did brownies, biscotti, sugar cookies and all the others I made.

I'm tossing the sprays.
