A Peruvian power food-infused pie that's healthy and delicious.
Preheat the oven to 400 degrees.
Measure 1 cup of the pichuberries. Place them in a medium saucepan with ½ cup water. Cover and bring to a boil.
In a small bowl, whisk together the cornstarch and the 2 tablespoons of water.
When the pichuberries and water have come to a boil, lower the heat and simmer, stirring constantly for 3 to 4 minutes, or until the pichuberries start to burst. Stirring constantly, add the cornstarch mixture, sugar, lemon juice, and salt. Simmer for a minute or until the mixture becomes translucent. Immediately remove it from the heat and quickly fold in the remaining 2 cups of pichuberries.
Spoon the mixture into the prepared pie shell and let sit at room temperature for a few hours before serving.
