I use mine all the time. Tonight I’m using it for the apple crisp- it will bake at the right time and the right temperature, but I’ll pop it on the warming tray while I serve dinner so I don’t leave it in the oven too long and watch the sugars caramelize and make the pan impossible to clean!
Any recipe you make regularly that calls for something served warm… but is a MESS to clean up if it stays in the oven too long-- better on the tray!
