My mother makes wonderful pies. She has the lightest touch with pastry. Mine turns out heavy and tough, so I rarely make pie even though I love it. Especially this time of year when the fruit is so gorgeous. I tend to overwork the dough when I mix it by hand. DH makes a better pie pastry than me, because his hands are strong enough to mix the dough quickly. I found a food processor recipe that works better for me, because the mixing takes seconds.
Here's the recipe:
3 cups all purpose flour
1 tsp salt
1/2 cup cold butter, in cubes
1/2 cup cold lard, in cubes
1 tsp vinegar or lemon juice
In food processor, blend flour and salt. Using on/off switch, cut in butter and lard until mixture is crumbly. There may be a few larger pieces left in the mixture.
In a measuring cup, beat egg until foamy. Add vinegar and enough ice water to make 2/3 cups liquid. With motor running, add liquid all at once to flour/butter mix in the food processor, just until mixture holds together. Don't let it form a ball.
Remove from food processor. Separate into 2 balls and flatten each into discs, wrapped in plastic wrap. Refrigerate for at least 30 minutes. Roll out dough on floured surface.
Can be stored in refrigerator for 3 days, but allow to rest at room temperature for 15 minutes before rolling out.
N.B. I like this recipe because it has no sugar, so it works well with sweet and savoury (meat) pies.
Good luck with the pie!
