Our household’s latest kitchen gadget is a tortilla press. Any tips on using one, for the uninitiated? I’m mostly hoping to make tortillas with it but maybe eventually also arepas.

@justip this is the best tutorial on making tortillas I’ve seen and I’ve successfully made excellent tortillas this way. It’s not difficult, but it is a skill that’s most easily learned by carefully observing someone doing it correctly.
I use plastic from an old 4.5 kg rice bag as covers. Should be food safe and is nice and thick.
Big ziplocks should also work fine.
