Sounds like they might be drying out, maybe while they’re waiting to be cooked. You can keep them under a moist towel while waiting if that’s the issue. They might also be cooking too long. I don’t have a great sense of what doneness looks like for tortillas, but I imagine knowledge mostly comes from experience.

Post pictures when you get a good batch!

Try using lard or shortening instead of oil, like this:

Yeah I’ve never seen tortillas made with oil. That’s too much liquid. You need shortening or lard.

Alternately, try making corn tortillas. Much easier and tastier.

Need a better fat for this application. Also you didn’t specify hot water, which is essential according to every abuelita I’ve talked to about it.

Can you share the recipe you are using?

I make tortillas almost every week and use flour, salt, baking powder, vegetable oil and warm water. The thing with tortillas though is that you have to go by feel. I hand knead the dough and have to know when to add more oil, water, or flour based on the consistency of the dough. It’s something you learn with trial and error.

There’s also an old wives tale that says your tortillas will never turn out properly if you are in a bad mood when you make them!

This is my goto recipe. I use the butter variant and they’re fluffy, chewy and perfect every single time. I used to use a press, but didn’t care for how small the tortillas ended up so I mostly smash the dough balls with a large pan or something similarly silly.
