I can't find this on the net, but it was there once. I've found some recipes that are very close though. Mine uses my Bosch which is way easier than the recipe using the exact same ingredients, but you cut the flour into the shortening by hand. That's fine for a crust or two, but 20? Yikes!
20 Pie Crusts in the Bosch
3 lbs Crisco (I've been using the butter flavor)
5 lbs all purpose flour
2 T salt
3 cups ice water (I fill a 4 cup measuring cup with ice, add water, then when I'm ready for it I scoop out the ice and adjust to get 3 cups)
Put the Crisco in the Bosch and mix on speed 1. Add the salt, then slowly begin adding the flour (too fast and you'll have a mess!). Pour in water as needed to keep it mixing well and alternate water and flour.
When all is mixed, begin dividing it into balls. If you have a scale, you want each ball to be between 7 and 8 ounces. Flatten slightly like a hamburger patty and place on waxed paper on a cookie sheet. Put in freezer. When they are frozen, like several hours later or the next day, move them to a couple of gallon ziploc bags.
When you are ready to use them, take out what you need and allow about 20-30 minutes to thaw. Roll out as usual and enjoy!
Not the healthiest ingredients, but at least there are no dyes!
