• 2 tablespoons unsalted butter, cut into bits
• 1/4 teaspoon cinnamon

• an egg wash made by beating 1 large egg with 1 tablespoon water
• about 1/4 cup red currant jelly, melted

1. In a large bowl blend the flour, the butter, the vegetable shortening, and the salt until the mixture resembles meal.
2. Add 2 tablespoons ice water, toss the mixture until the water is incorporated, adding more ice water if necessary to form a dough, and form the dough into a ball.
3. Dust the dough with flour and chill it, wrapped in wax paper, for 1 hour.
4. Roll out the dough 1/8 inch thick on a lightly floured surface, fit it into a 9-inch (1-quart) pie plate, and crimp the edge decoratively.

9. In a large bowl stir together the brown sugar, the flour, the butter, the cinnamon, the walnuts, and a pinch of salt and blend the mixture until it resembles coarse meal.
10. Spoon the filling into the shell, sprinkle the streusel topping around the outer 2 inches of the filling, leaving the center exposed, and brush the edge of the shell with some of the egg wash. Bake the pie on a baking sheet in the lower third of a preheated 450F.
11. oven for 15 minutes, reduce the heat to 350F., and bake the pie for 50 minutes to 1 hour more, or until the filling is bubbling and the rhubarb is tender.
