Total time: 30 minutes plus overnight
Puree fruit and 1/2 cup water in blender until smooth; strain out seeds.
Place 2 cups puree in a heavy-bottomed medium saucepan. Thoroughly mix pectin and 1/4 cup sugar, whisk into fruit puree, and bring to a boil over medium-high heat. Add remaining 2 1/4 cups sugar and cook mixture until it reaches 225°, stirring constantly. Stir in lemon or lime juice; cook 30 seconds more.
Pour into a lightly oiled 9" x 13" baking pan, sprinkle sugar on top, and allow to set, about 2 hours. Cut into 1-inch squares, or use a lightly oiled cookie cutter to make other shapes. Dredge in sugar and dry on a cooling rack overnight. Scraps can be remelted and reset.
Store in a box or paper bag at room temperature for up to two weeks.
