Plum-Blackberry Streusel Pie

Last night I was home alone, so I felt like baking would be a fun activity. I've also been wanting to try my beautiful new Emile Henry pie dish that my sisters-in-law-to-be gave me as a shower present. (Thanks, guys!) This Plum-Blackberry Streusel Pie sounded great, so I braved the heat (not as bad as earlier this week), turned on my oven, and baked. What a pretty pie!

Ingredients:

4 large, pitted and quartered

2 cups blackberries

1 1/2 cups sugar, divided

3 tablespoons quick-cooking tapioca

2 tablespoons cornstarch

1 teaspoon grated lemon zest

3/4 teaspoon salt, divided

1 frozen pie crust (I used one from Trader Joe's)

1 cup old-fashioned rolled oats

1/2 cup all-purpose flour

1 stick cold unsalted butter, cut into bits

Directions:

Put a foil-lined large baking sheet in lower third of oven and preheat oven to 375°F.

Toss plums and blackberries with 1 cup sugar, tapioca, cornstarch, zest, and 1/4 teaspoon salt in a large bowl.
