Parchment Paper
I have a couple of Wilton four-cavity loaf pans that look like they should be a "quick-release" version.
They are NOT! It was very frustrating having half of each loaf remain in the pan!
I finally learned that parchment paper is, indeed, my friend.
I have started lining the entire cavity with parchment paper and the loaves plop out as slick as can be !
It is a bit of a bother doing so, but not nearly as aggravating as having the bread stick to the pan.
