Why do my macarons come out looking weird?
Ah, macarons. If it's not one thing, it's another. Uneven pied usually indicate that the oven was too hot. You should use an oven thermometer to determine the exact temperature of your oven, because oven dials themselves straight up lie. I once had an oven that was always 20C over the temperature on the dial.

If you get a thermometer (or have one) and this still happens, try positioning the tray at different heights in the oven.

Unfortunately, making macarons is a process of trial, error and experience, getting to know your oven and the texture of the batter. Good luck.
