In a mixing bowl, add flour, baking powder, salt and mix.
Using your finger, rub lard or oil, in the flour until mixture resembles small crumbles throughout.
Add sourdough discard, and hot water, and mix until dough starts to form.
Let rest for 10 minutes.
Knead dough in the bowl or on a clean surface - you should not need to dust work surface with flour.
Once dough ball is smooth, cover & let rest for 30 minutes.
Divide dough into either 12- 16 smaller sized tortillas or 8 large.
Roll each piece into a ball, and cover for 20 minutes.
Roll each ball out, as thinly as possible. Cooking as you go.
Preheat pan on medium - high heat.
Once pan is hot, place tortilla in pan for 30 seconds each side. Careful not to cook too long, they will get hard! If needed you can grease your pan with a very small amount of lard or oil.
Wrap tortillas up in a tea towel, or basket and serve!
If you are wanting to store them, allow them to cool and place parchment between each one and freeze in a sealed container or bag.
