This recipe is dedicated to my dear friend Veronika in Berlin who once made me a rhubarb cake in May and froze it until we could eat it together in September. She is wild about rhubarb and if a menu even hints at the rhuby fruit she will order it.
Minnesota Rhubarb Pie
Crust:
2 1/4 cups flour
1/4 tsp salt
1/2 tsp cardamom
1/3 cup sugar
1 1/2 cups butter cold and in small cubes
1 tbsp ice water
Filling:
3 1/2 cups rhubarb cut in small pieces
1 zest of lemon
1/4 cup sugar
1/4 cup maple sugar or regular sugar
2 tbsp tapioca starch
Directions:
In a food processor combine dry ingredients for crust and mix well. Add butter and pulse until dough begins to form pea-sized crumbles. Turn into a mixing bowl and sprinkle with water. Gently fold and press dough until it forms a ball. Cut ball in half, form into a disk and wrap in two pieces of plastic wrap. Place in refrigerator for 45 minutes.
In a mixing bowl add all the ingredients for the filling with the exception of the tapioca starch. Mix with a spoon until rhubarb is coated evenly in sugar and allow to sit for 45 minutes to macerate.
Preheat oven to 425ºF. Take one half of dough from the fridge and roll it out into a disk a little less than a 1/4 inch thick. Drape into a 9 inch cake pan and cut edges just at the point that they come past the sides of the pan. With aluminum foil pressed gently against the bottom of the crust and against the walls fill the bottom of the aluminum lining with pennies or rice and bake. After 10 minutes take the foil lining out and bake for 5 more minutes until the crust is pale. Take crust out of the oven and allow to cool for a moment.
Add tapioca starch to pie filling, mix well and pour into shell.
Roll out the second crust to less than a 1/4 inch thick and cut into strips and create a lattice on top of the pie crust. Tuck the edges of the strips behind the shell crust. Brush with milk.
Bake pie at 425º for 15 minutes. Reduce heat to 350º and continue to bake for 35-40 minutes or until the filling is bubbling and top crust is golden brown. If edges brown too quickly, cover them with aluminum foil. Allow pie to cool for at least one hour. With a plate on top of the pie, quickly and gently turn it upside down. Take off the cake pan and quickly turn it back onto a second plate or cake stand. Be sure not to crush the pie with the second turn. Sprinkle with powdered sugar and serve with ice cream or whipped cream.
