- Parchment paper
- 2 cups frozen strawberries, defrosted
- 1 3/4 tablespoons apple pectin powder (found at health food stores)
- 2 cups plus 2 tablespoons sugar, divided
- 3 1/2 tablespoons light corn syrup
- 2 teaspoons lemon juice
- Line a rimmed 9″ x 12″ baking sheet (with at least a 1/4-inch rim) with parchment paper. Puree strawberries in a blender until smooth. Mix pectin and 3 tablespoons sugar in a bowl. Transfer puree to a 2-quart saucepan and bring to a boil over medium-high heat. Sprinkle pectin-sugar mixture onto puree and stir until pectin dissolves. Continue to boil for 2 minutes. Add 1 3/4 cups sugar in 3 parts, stirring after each addition and waiting 15 seconds between additions. Add corn syrup; cook mixture until it thickens slightly, about 3 minutes. Remove from heat; stir in juice. Pour mixture into baking sheet, spread evenly and let set 2 hours. Cut jelly into 1-inch squares or other shapes using a sharp knife. Toss squares, a few at a time, in remaining 3 tablespoons sugar. Store at room temperature in an airtight container for up to 1 month.
