Strawberry Pretzel Pie

For the pretzel crust: Preheat the oven to 350 degrees F. Crush the pretzels in a large resealable plastic bag with a rolling pin. Mix in a bowl with the butter and brown sugar. Press into a pie pan and bake for 8 minutes. Remove and set aside to cool. For the strawberry filling: Put 1 1/2 cups water, the granulated sugar, cornstarch and gelatin powder in a saucepan. Stir together and bring to a boil. Reduce the heat and cook until it starts to thicken, about 2 to 3 minutes, then remove from the heat. Let the liquid cool for a good 10-15 minutes, stirring occasionally. Put the strawberries in a bowl and pour over the sauce, gently tossing together. Allow to sit for 5-7 minutes, then carefully pile the coated strawberries into the cooled pie crust. Spoon over a little leftover sauce if needed, and refrigerate, uncovered, for 4 hours. Cut into slices and serve with whipped cream. (Unsweetened is nice because the pie is so sweet!)
