Hi, I am having serious trouble with my macarons forming nice feet except on one side, which always sticks. I have tried dozens of times, tried various oven temperatures, placing them to dry in various conditions with no breezes to dry one side of the cookie, vent on and vent off in the oven. I pipe them at 90 degrees and the shells are lovely, smooth and round. But they always bake lopsided and each one sticks on different sides, not just one side. Any help would be so appreciated! Thanks!
