Ingredients
Method
- Peel, core, and slice the apples into 1/4-inch thick pieces, then toss immediately with the lemon juice to prevent browning.
- In a small bowl, whisk together granulated sugar, brown sugar, cornstarch, cinnamon, nutmeg, allspice, and salt until no lumps remain.
- Pour the water or apple cider into a large heavy-bottomed saucepan over medium heat. Gradually whisk in the sugar–spice mixture and cook, whisking constantly, until the sauce thickens and turns glossy, about 2–3 minutes.
- Fold the apple slices into the thickened sauce, ensuring every slice is coated. Reduce heat to medium-low and simmer, stirring occasionally, until the apples are just tender but still hold their shape, 6–8 minutes.
- Remove the pan from the heat. Stir in the butter until melted, then mix in the vanilla extract.
- Let the filling cool at room temperature for at least 30 minutes before using in pies or transferring to storage containers.
Notes
For best flavor, use a mix of tart and sweet apple varieties such as Granny Smith and Honeycrisp. The filling can be refrigerated for up to 7 days or frozen for up to 12 months. If planning to can the filling, replace cornstarch with Clear Jel for safe, shelf-stable results.
