I would like to learn more about your home made Taco shells. A long time ago my Mom used to make them. A lot of work but so good 
They're really simple to make. The authenticity might be questionable since I don't use lard. But they tastes better than any store bought.
For your first batch try this
1 Cup all purpose flour
2 tablespoons fat of your choice. I prefer solid as in butter, chilled bacon fat, coconut oil.
A pinch of salt
About 6 tablespoons warm water or chicken stock (more flavor )
Mix the salt and flour then rub the fat into the flour. Get as much flour to cling to the fat.
Then add water, little at a time until you can get the mixture into a cohesive ball.
Knead that for about minutes just to get things together. Tightly Wrap that in a plain and let it sit for about 30 minutes.
Sometimes I divide into balls right after kneading then give them a rest.
Divide into small balls, roll out and heat..
