Bring 1/4 cup light corn syrup, 2 tablespoons butter, 1 cup confectioners' sugar, 1/2 cup plum jam, 1 cup mini marshmallows and 1 tablespoon water to a boil in a large pot over medium heat, stirring. Add 1/2 teaspoon almond extract and a pinch of salt. Remove from the heat; using a rubber spatula, stir in 12 cups popcorn until coated. Butter your hands, then shape into balls and roll in coarse sugar.
