These are surprisingly easy. And if you look at the ingredients list of a supermarket tortilla, you will likely want to go with this. (Not to mention, these taste way better.)
0.75 tsp salt
0.25 tsp baking powder
0.25 cup shortening
0.5 cup hot water
Whisk the flour to combine with the salt and baking powder. Mix in the shortening by hand, until the mixture is crumbly.
Pour in the hot water (not boiling, but pretty hot). Mix immediately until it comes together, knead until smooth dough forms.
Cover with a bowl and allow to rest for 20 minutes. Cut into six pieces.
Roll each ball into a large circle. Cook in a medium-hot, preheated, dry skillet for 50 seconds on the first side and 25 seconds on the other. If you cook it longer, it dries out, and won't be soft.
