I have two different types of baking sheets, one stainless steel, cost more, from (I think) Williams Sonoma bought years ago, the other from Target, a teflon coated Kitchenaid one that's under $20, fairly new. Using the same batch of cookie dough and same type silpat mats, same everything else, the cookies on the stainless ones end up flatter while the teflon ones end up taller, puffier. They look like two totally different cookies. The flatter ones tastes chewier while the taller ones are cakey. Does anyone know what causes the difference?
The dark Teflon surface accepts heat faster, but the material under the Teflon also plays a part. If the Teflon coated pans are giving you problems, then I would bake all the cookies on the SS pans. I am not a fan of Teflon lined baking pans and have no bought a Teflon lined cooking pan in years.
Did you use a parchment liner to level the differences?
I use silpat mats. The teflon were an impulse buy because I was at Target and was going to bake a huge quantity of cookies. They were the best they had. I hate waiting for the sheets to cool. If I can't find a way to make the Teflon work, I'll get rid of them. But, I was hoping there would be a way to solve it, like refrigerating the dough on the tray first. It really is convenient having 4 cookie sheets but I'm too cheap to buy more stainless. I might look into the ones you recommended. Thanks!
If you are determined and can work scientifically, I have no doubt you can produce a cookie with the non-stick that looks and tastes the same as the SS.
Refrigerating the dough and pan might be worth a try (your thinking is sound) but remember that you are only cooling it about 40 degrees less than room temp and then heating it to about 270 degrees above and the mass of the pan is very small so the 'effect' may only last a few seconds.
The primary variables are time and temp. A good oven thermometer is a start. Don't forget that the position of the pan (shelf) is very important. Also, don't put two pans in at once. Although if you do you can see the difference shelf height has.
You can also play with the dough consistency. By modifying slightly the amount of liquid or solids.
Is all this testing worth it? Only you can decide. Good luck.
