Have been making bagels at home and they taste great but I just can't keep them from sticking to the baking sheet when they're done. I've tried greasing the sheet with butter, greasing it with oil and a bit of flour as well as putting down parchment paper with some oil on top (that was the worst - paper completely stuck to bagel). They stick so much that by the time I've scraped them off of the tray, all of the toppings and a good chunk of the bagel are stripped from the bottom.
I've always tried to remove them from the tray when they just come out of the oven. Is that the problem? Do I need to let them cool first or is there something else I should be doing?
