Yeah, in researching recipes, they’re about 50/50 for and against adding fat. The hardliners say never to add fat as it’s unnecessary, but others say add some lard or butter to increase the pliability. The ones I made are still fairly pliable, they have a crackly surface but don’t actually crack or tear when folded.
Honestly the tortillas are the easiest part, the dough is easy to work with and not messy, as long as you have a tortilla press it only adds around 20 min to the total cook time.
Maybe you could freeze them? I haven’t tried it, but I know they get moldy after like 24 hours if you try to make them ahead of time.
Everything sour is acidic, the sour taste comes from the hydrogen ions (protons) donated by acids blocking the potassium ions leaving your taste buds, this creates a depolarization and opens voltage gated calcium channels, the influx of which causes neurotransmitter release. Sour gums/candies don’t contain Acetic acid (vinegar) but instead Citric acid and sometimes Malic acid.
