Instructions
- Prep. Preheat the oven to 400 degrees Fahrenheit (204 degrees Celsius). To make cleanup easier, line a baking pan with aluminum foil. Sprinkle some flour on the pie plate and gently place the bottom crust, then carefully put the bottom crust into it, cutting off any excess.
- Make the Filling. Combine the blackberries, raspberries, and sugar in a large saucepan over medium heat. Stir for around 5 minutes until the sugar dissolves and the berries release their juices. Once done, taste the mixture and add more sugar, if needed, one tablespoon at a time. Mix cornstarch and lemon juice in a separate bowl to make a smooth slurry. Gradually pour this mixture into the simmering berries while stirring continuously. Continue to cook and stir for 2-3 more minutes until the mixture thickens slightly.
- Assemble the pie. After preparing the berry mixture, let it cool for 10 minutes so the bottom crust doesn't become soggy. Then, pour the slightly cooled berry filling into the pie crust that you have prepared. Cover the filling with the top crust and seal the edges by crimping with a fork or your fingers. Make small slits in the top crust to allow steam to escape. Finally, brush the top crust with milk and sprinkle coarse sugar for a shiny and sweet finish.
- Bake. Put the pie on a baking sheet you've prepared earlier and bake it in an oven that you have preheated for 40-45 minutes. Make sure it turns golden brown and the filling bubbles through the slits. If the edges of the crust become brown too quickly, cover them with foil strips or a pie crust shield halfway through baking.
- Chill and serve: After baking the pie, put it on a cooling rack and let it cool for about 2 hours at room temperature. Then transfer it to the fridge and let it chill throughly before serving. If you skip this step, it will be very runny.

Notes
Five years ago we put in some apple trees and a bunch of berry bushes. The apple trees have been… interesting (nope, still no apples), but the berries? They’ve been perfect.
Every June and September, we get blackberries and raspberries at the same time. And that means pie. It’s actually become one of those simple traditions we look forward to twice a year.
More Tips
If you prefer very sweet pies, add more sugar to this recipe. I suggest starting with 1 cup, but adjusting to your taste is up to you. The sweetness of the berries may vary, so taste the filling before adding more sugar. If you prefer it less sweet, one cup of sugar may be enough.
Coarse sugarย that will hold its shape in the oven gives the crust a yummy sweetness and crunch.
Frozen berries work well in this recipe, but of course so does fresh.
Adding lemon juice to the filling brightens the flavors of the pie. But be sure to zest them first and save the zest.
