Cut each phyllo pastry sheet into six squares, about 4 inches each. Layer six squares of phyllo pastry in each of six muffin cups, brushing each layer with butter and placing the corners of the squares to create a petal effect. Bake at 375 degrees F for 10 minutes or until phyllo is crisp and lightly browned. Brush bottom of each pastry cup lightly with honey, using about 1 tablespoon among the 6 cups. Remove phyllo cups from muffin pan and cool on baking rack. Toss grapes with liqueur and remaining 2 tablespoons honey. Mix well and let stand 30 minutes.
Note: You may use whipped cream cheese or prepared vanilla pudding instead of yogurt, if you prefer. Roll remaining phyllo from the purchased package in waxed paper; then in plastic wrap and store according to package recommendation.
