Question: Do these work well with Silpat baking mats? I have been using a jelly-roll type pan for baking  but Silpat mats are too large so I need a flat sheet.
Document: I have used the pans several times and they bake my cookies great. I have tried it with a silicone mat and parchment paper. both worked very well. The pan is easy to clean.But...After a few baking sessions, the pan has warped. not severely, but enough for me to notice when putting on a flat surface. I have not noticed it having any effect on the baking ability.I found you need to put something between the pan and the cookies though.
I needed cookie sheets and just went on line to search. I chose two types: the flat with turned up edge and the type with edges all the way around. After I received this cookie sheet I discovered that it is great for removing pizza from the oven especially when baking on a baking stone that I also purchased through Amazon.
I love these suckers. I bake a lot of cookies during the winter, and these work really well. My oven runs kinda hot, so i'm constantly playing with temps and baking times when trying new recipes, and these save my cookies. Cookies brown much slower when baked on these, and they don't stick nearly as badly. I'd buy these over and over again, but won't need to, because mine have held up beautifully to all kinds of abuse.
Love them. Nice large  size product. And they  fit perfectly in the oven. Will enjoy using them with a lot of baking
If you want an aluminium insulated pan this is it. I recommend seasoning the surface before use:1. clean with dish soap and dry well2. cover with one T of oil and rub well into surface3. wipe extra oil off4. bake at 400 degrees for 15 minutes5. buff off remaining oil6. repeat until your buffing towel has no dark aluminium oxides on the surface.7 if you need to start from scratch, use 0000 steel wool to prep the surfaceEnjoy.
These pans work pretty well. They stick some but not as bad as other pans I have used. I use non-stick pan with them usually. Biscuits seem to stick the most.
This pan bakes throughly but makes my cookies flat. I even attempted placing parchment paper on top of the pan to see if that would help but did not. I use this pan for baking pizza dough, biscuits, and if I purposely want flat cookies.
I've used these pans twice now, and love how the cookies turned-out, but if I were to do this over again, I would not purchase this type of pan. I always use parchment paper when baking cookies, and since this pan does not have raised edges on all four sides, the parchment paper and cookies seem to want to fly off the sheets when I remove them from the oven. Several times the cookies almost ended-up on the floor.
For general use, these pans are fantastic. As promised the bottoms of cookies come out perfect, and not overbaked. I do like that there's a lip on only one edge, allowing you to slide items off if you need to. It also allows parchment or silpat to hang over the edge if needed.Where these pans really shine is in baking french macarons. After struggling for batch after batch, I think I've finally found the solution I was looking for.
These pans replaced some aging pans of similar type. They simply work great and the old ones are used for catching overflow from pies or other baking to make oven clean up easier.
Answer: Yes. Excellent combination! DO NOT WASH IN DISHWASHER!!!!
