For berry topping, in a medium saucepan combine 1/4 cup granulated sugar, cornstarch, and salt. Stir in the water. Stir in 1/2 cup of the berries. Cook and stir over medium heat until thickened. Remove from heat. Add an additional 1 cup of the berries and the 1 teaspoon butter, stirring until butter
is melted. Gently stir in orange peel.
In a medium bowl combine cream cheese and orange marmalade; beat with an electric mixer on low to medium speed until smooth. In a small bowl stir together the 2 teaspoons granulated sugar and the cardamom.
Toast the split pita rounds. Brush pita rounds with the 2 tablespoons melted butter; sprinkle with the sugar-cardamom mixture. Spread cream cheese mixture over split pita rounds. Spread berry topping over cream cheese mixture. Top with the remaining 1/2 cup berries.
