Cran-Apple Jellies

Step 1

Line an 8x8” baking dish with parchment paper, leaving overhang on 2 sides. Purée apple, cranberries, 1½ cups sugar, and 1 cup water in a blender until smooth. Transfer to a large deep heavy pot fitted with thermometer and cook over medium heat, whisking occasionally, until mixture is very thick and bubbly (it will sputter and splatter as it cooks; reduce heat if needed), 8–10 minutes.

Step 2

Whisk pectin and remaining ½ cup sugar in a small bowl, then gradually whisk into cranberry mixture. Reduce heat to medium-low and continue to cook, whisking often, until thermometer registers 200°, 15–20 minutes (mixture will be dark red and extremely thick).

Step 3

Whisk lemon juice into cranberry mixture, then scrape into prepared pan; smooth top. Let cool until set (it should feel firm when you gently press it), at least 4 hours.

Step 4

Just before serving, unmold jelly onto a cutting board and cut into 1” squares. Toss jellies in sugar to coat.

Step 5

DO AHEAD: Jelly can be made 1 week ahead. Store in pan, tightly wrapped, at room temperature. Cut and roll in sugar just before serving.
