Recipe(tried): Nut Pastry Dough

From Eating Well - Nut Pastry Dough recipe does taste wonderful and I use frequently:
Recipe is for Small Single Crust:
1/4 cup walnuts/hazelnuts/almonds or pecans
1 cup all-purpose flour
1 Tbspn. sugar
1/2 tsp. salt
1 Tbspn. cold butter, cut into pieces
1 1/2 Tbspn. oil
4 Tbspn. cold water

Preheat oven to 350F. In food processor, combine nuts, flour, sugar, and salt; process until nuts are finely chopped. Add butter and process until incorporated. Transfer to large bowl. Drizzle oil over flour mixture. Use your fingertips to rub oil into the mixture. One tablespoon at a time, add water and mix with a fork until dough is crumbly and holds together when presssed. If making a single crust, gently form dough into a flattened disk. If making a double crust, divide dough into 2 pieces, 1 slightly larger than the other and form each into a disk.
The dough will keep tightly wrapped in plastic wrap in the refrigerator for up to 2 days or in the freezer for up to 6 months.
