i tried the link and it was fine. not sure why it didn’t work for you.
what’s interesting is that after dissolving the cornstarch and water, the mixture is frozen for 10 minutes, then added to the flour, sugar and salt already in the food processor. after the cornstarch is distributed, cold butter and 2 tablespoons of sour cream are added. when mixed, they form the dough. this is a completely different way of making pie dough.
oh, when i reread the recipe, i realized that the cornstarch slurry was supposed to be microwaved 30-40 seconds.
