Still a battle to find the right bake after almost a year of tweaking they are still browning but so close! Learned so much

I started my journey for my daughter’s wedding favors and got obsessed. Low sugar recipes and my 3 yr old kitchen aid oven has given me the biggest challenge, the fan sets the outside too fast it cooks the outside before the inside could set properly and also trapped moisture. Convection bake and reg bake both have fans. I made adjustments and need to mix EW to med/stiff peaks, and my ribbons melt at 8-10 sec. Gave up EWP and COT both made the outside shell to firm, go figure. I also gave up on silpat as much as I love the bottoms and perfect round shells I would only get hollows. Silpat takes longer to heat and it is not porous as teflon, it traps the moisture in my shells that set too soon and creates the hollows even though everything looked amazing on the outside. It was almost like my shells were too perfect for my aggressive oven 😂 if I bake at 275, 21 min, oven shower 2 min. I would get perfect color but still sticky bottoms, any longer brown shells. The heat is just not high enough to bake bottoms.

So today I baked them at 300 for 1 min on #2 rack with stone just below the shelf, dropped temp to 275 after that 1 min, at 6 min rotated tray to middle rack with baffles to protect from fan. Baked for 17 min, they are slightly brown and I believe they could have come out after 16 min and been perfect. I hope to have success after the next batch just in time to have perfect cookies for the May wedding 😮‍💨😵‍💫. The picture is my shell rested 40 min and my oven set up.
