What kind of tray or tray coating to use for pretzels? I've been making traditional German pretzels with a lye bath, but the pretzels tend to bake onto the baking sheets. I've tried a few different kinds of trays, all with less that perfect results. 


Non-stick coatings actually stick to the bottom of my pretzels and
get pulled off the trays.
Some pans without coatings react visibly with the lye solution, i.e.
bubbling. Unfortunately, I'm not sure which metal this pan was made
of. On the other hand, the pretzels stick less.
Wax paper sticks to the degree that I have to cut it off.


I would like to find a solution that prevents my pretzels from sticking and me from ingesting any Teflon, metal, or paper.
You need a Silpat! I recommend a half sheet size Silpat and a Stainless Steel Half-Sheet Pan.

A Silpat is a silicone mat. It's the most non-stick way to bake anything, and they're quite durable. Buy a couple of mats and you can just swap them out when baking multiple batches. 

According to folks at The Fresh Loaf the silicone shouldn't react at all with the lye.

Aluminum reacts badly with lye, so be sure that nothing you use with the lye contains aluminum.
