Ingredients Needed For This Blackberry Pie Filling Recipe

Whole Blackberries– Fresh blackberries are the star of this recipe. Opting for fresh berries ensures your filling is bursting with flavor and natural sweetness. While I’ve used frozen blackberries (a great alternative when fresh isn’t in season), it’s essential to avoid canned berries in sweetened juice, as it alters the taste and consistency of your filling.

Salt – Believe it or not, a pinch of salt is key in baking, especially in sweet dishes. It enhances the natural flavors of the ingredients, making the blackberries taste even more sweet and vibrant. Don’t skip this; a pinch is all you need and a little goes a long way.

Lemon Juice – Lemon juice adds brightness and balances the sweetness of the blackberries and sugar. It brings out the depth of flavors, adding a slight tang that complements the berries beautifully.

Sugar – Sugar does more than just sweeten the filling; it helps draw out the natural juices of the blackberries, contributing to the syrupy consistency that makes pie fillings so delightful.

Cornstarch and Water – This combination is used to create a slurry that thickens the filling, giving it the perfect consistency that holds together well inside your pie or dessert, without being too runny or too thick.

Where to Use Fruit Pie Fillings

  • Blackberry Pies and Hand Pies: While fruit pies are always a classic dessert, fruit turnovers are ideal for a portable, mess-free dessert.
  • Fruit Tarts: Adds a rich, decadent layer.
  • Layered Dessert Cups: Perfect for a visually stunning and delicious treat.
  • As a Topping: Over cheesecakes (like my 3 Ingredient Cheesecake recipe), pancakes, or waffles for an extra burst of flavor.

Tips and Variations to This Berry Pie Filling

  • Add Other Berries: Mix in strawberries, raspberries or blueberries for a multi-berry filling.
  • Rhubarb: Adding rhubarb is always a fun, tart addition to the berries as well.
  • Add a Kick: A dash of cinnamon, and nutmeg for some warm flavors, but if you want to add a small kick and extra sweetness, try adding some Hot Honey to the mix!
  • Combo Fruit Fillings: Combine with peaches or apples for a unique twist.
  • How to tell when the filling is ready: After you’ve added the cornstarch slurry, it should be thick enough that you can run your finger through the filling on the spatula and it leaves a solid line where your finger was.

Storage and Freezing

This filling can last up to 5 days in the fridge if it has a tight fitting lid on the container.

For freezing, it’s best to leave out the cornstarch slurry until you’re ready to use the filling. Freeze the berry mixture alone, and when thawing, add the slurry as you reheat it to ensure the perfect consistency. This approach helps to prevent the filling from possibly thinning out if you thicken it before freezing.

Questions You Might Have

1. Can I use frozen blackberries for this pie-filling recipe?

Absolutely you can! Often, I prefer to use frozen fruit because it’s frozen at its peak freshness. However, if you have freshly picked berries or you’ve found a great deal on store-bought fresh blackberries, they might be a cheaper alternative than using frozen.

2. Can I water bath this filling after it’s made?

Yes, you can and I recommend using Binky’s Culinary Carnival’s tutorial on how to water bath the filling safely.
