1-1/2 batch of my pie crust and this filling is just enough to make two 10 inch pies. If you have one of those deep-dish pie plates, you will get a single pie. The lattice pattern requires more dough than a flat top pie, but it is worth the effort, because the large vents help the moisture bake off and true lattice top will stay intact when you serve the pie. Watch the instructional video. I sprinkled a tiny amount of nutmeg on the fruit, it is not even detectable, I don’t think rhubarb needs a flavour boost and so I would never add cinnamon.
The following recipe makes two 10 inch pies or one large deep dish pie:
1-1/2 batch of pie pastry
4 cups chopped rhubarb
4 cups chopped strawberries
1-1/2 cups yellow sugar
1 pinch of nutmeg
1/3 cup quick cooking tapioca
1/4 tsp salt
Added to filling later:
1/4 cup cornstarch
1/2 cup butter
1 lightly beaten egg for glazing the lattice top
1-1/2 Tbsp sugar for sprinkling the lattice top
• Place a baking pan with a rim preferably on the lower rack of your oven, provided you have two racks. If not, place the catch tray on the rack anyway. This will catch the overflow. The catch tray saves you having to clean the oven the day after you made the pie. Beware, never place a catch tray on the very bottom of an electric stove! This can blow out your bottom element.
• After the catch tray is in the oven, preheat to 400F.
• Wash and clean up the fruits.
• Cut and discard the ends and chop the rhubarb into small pieces [huge chunks of rhubarb are unappetizing]
• Cut and discard the top the strawberries and chop trying to match the rhubarb pieces in circumference.
• Combine the filling ingredients in a large bowl and set aside.
• Before rolling out the pastry, keep in mind you will need more dough for the lattice pattern than for the bottom layer. The bottom layer has to be thick about 3/8-inch thick and large enough for 1 inch of overhang.
• On a floured board, roll out the bottom pastry into a circle.
• Place the dough circle into the pie plate.
• Pat the dough into the pie plate.
• Fold the overhang back into the plate rim. This will form a ridge on the rim. Pat it down.
• Sprinkle 1/4 cup of cornstarch around the bottom.
• Add the prepared filling and arrange it neatly into a small dome.
• Dot the top with small chunks of butter.
• On the floured board, roll the dough 3/8-inch thick.
• Using a ruler for guide cut the rolled out dough into 1-inch wide strips. I used a ravioli cutter, but a pizza cutter or a sharp knife will work as well.
• To make the lattice pattern
• Start at the center with the longest strip and work outwards.
• Place half the strips, spacing about 1 inch apart, on top of the filling.
• Then, gently fold back, about halfway, every other strip.
• Take another strip of pastry and place it perpendicular on top of the first strips.
• Unfold the bottom strips and then fold back the strips that were not folded back the first time.
• Lay another strip of pastry perpendicular on top of the filling and then continue with the remaining strips.
• Trim the edges of the strips, leaving a 1-inch overhang.
• Seal the edges by folding them under the bottom pastry crust and flute the edges of the pastry.
• Brush the entire lattice pastry with egg wash and sprinkle with sugar.
• Bake for 20 minutes at 400°.
• Then, reduce heat to 350° and bake for another hour or longer as needed.
• Remove from heat and place pie[s] on a wire rack to cool.
• Chill thoroughly in the fridge before slicing. If the juices have not jelled, refrigerate overnight.
