If you want to make a big batch and freeze them...here's my recipe. After mixing, I just divide it up...(makes about 13 large shells)...roll into a ball and flatten. Wrap and put in the freezer. When you take them out you can either let them thaw, or place in the microwave about 30 seconds.
5 pounds flour
3 pounds lard
2 1/2 cups water
Contrary to everything I ever learned (lol)....we just place the flour in our 20 quart mixer with the lard....blend with the paddle....and when blended add the water slowly until mixed in. They always come out great, and are easy to handle. I bet for home, you could do half a recipe so you could have some extras in the freezer....though I'm not sure if that amount would fit in a 5 quart mixer.
You can close your eyes to the things you do not want to see, but you can't close your heart to the things you do not want to feel.
