Place berries in an even layer in a 9 inch pie plate or divide among 4 individual gratin dishes.

In a small bowl, whisk together cream cheese, milk and lemon juice. Spread over the berries, leaving the outer edge uncovered. Set aside in the refrigerator, covered with plastic wrap, for up to 1 hour.

Preheat the broiler. Press sugar through a coarse sieve over the berries, covering them evenly. Broil until the sugar has melted, about 4 minutes.
