Edit in reply to comments: I used margarine since I keep neither lard nor shortening around.
Why did I not try this sooner? I used a recipe I found online that seemed easy enough and it was. I halved the recipe and got 8 good sized tortillas. They are not exactly round but so much better than the store bought ones. There flavor is so neutral it does not interfere with whatever you put into them and their texture is great too. They do not get brittle and don't get holes when you roll them. And they really are not that much work at all. One more thing to remove from my shopping list forever. ;-)
