Ingredients
Scale
Fruits and Flavorings
- 6 cups fresh raspberries (about 3 pints) or frozen raspberries (thawed)
- 1 tablespoon freshly squeezed lemon juice
- 1/2 teaspoon vanilla extract (optional)
- Pinch of salt
Sweetener and Thickener
- 1 cup granulated sugar (adjust to taste depending on the sweetness of the berries)
- 1/4 cup cornstarch
- 1/4 cup cold water
Instructions
- Rinse the Raspberries: Gently rinse fresh raspberries under cold water, or if using frozen, ensure they are fully thawed and drain any excess liquid thoroughly.
- Combine Raspberries and Sugar: In a medium saucepan, gently stir together the raspberries and granulated sugar to evenly coat the berries with sugar.
- Simmer the Mixture: Place the saucepan over medium heat and bring the raspberry and sugar mixture to a gentle simmer, stirring occasionally to prevent sticking.
- Cook Down the Berries: Continue simmering for 8-10 minutes until the raspberries have softened and released their juices, stirring frequently to avoid burning.
- Smash Some of the Berries (Optional): For a smoother texture, gently mash some raspberries against the side of the pan with a spoon or potato masher.
- Whisk Cornstarch and Water: In a small bowl, whisk together cornstarch and cold water until completely smooth to create a slurry.
- Slowly Add Slurry to Raspberry Mixture: Gradually pour the cornstarch slurry into the simmering raspberry mixture while stirring continuously.
- Stir Constantly: Keep stirring constantly to incorporate the slurry evenly and prevent lumps from forming.
- Simmer and Thicken: Continue simmering the filling over medium heat, stirring constantly, for 2-3 minutes until the filling thickens enough to coat the back of a spoon.
- Remove from Heat: Once thickened to your desired consistency, take the pan off the heat to stop cooking.
- Add Lemon Juice and Vanilla Extract: Stir in the freshly squeezed lemon juice and optional vanilla extract to enhance the flavor complexity.
- Add a Pinch of Salt: Sprinkle a pinch of salt to balance sweetness and brighten the overall taste.
- Taste and Adjust: Sample the filling and adjust sugar or lemon juice if a sweeter or more tart flavor is preferred.
- Cool Slightly: Allow the filling to cool at room temperature before using; it will continue to thicken as it cools, perfect for your dessert applications.
Notes
- If a chunkier texture is preferred, skip mashing the berries.
- Use fresh lemon juice for the best bright and natural flavor.
- Adjust sugar amounts according to the sweetness of raspberries or personal taste.
- The filling can be refrigerated and used within 3-4 days.
- For a vegan option, ensure that vanilla extract used is vegan-friendly and consider alternative sweeteners if desired.
