Instructions
Place blackberries, sugar, lemon zest, and lemon juice in a small saucepan and cook over medium heat until the berries have broken down. Mash and stir with a wooden spatula as you go.
Once berries have thoroughly broken down, taste to see if additional sugar needs to be added. Add 1-2 additional tablespoons if desired.
In a small bowl, stir cornstarch and water together until completely combined.
Add cornstarch slurry to the berries while stirring, and continue to stir.
Bring mixture to a low simmer while stirring frequently. Be sure to fully scrape the bottom and sides of your pan as you go. Continue to cook until the filling has thickened.
Remove filling from heat. Place in the fridge to chill.
