In a small bowl, sprinkle gelatin over cold water; set aside. In a small heavy saucepan, combine milk, rice, sugar and salt; bring to a boil, stirring occasionally. Reduce heat; simmer, covered, 15-20 minutes until rice is tender. Remove from heat; stir in gelatin mixture until completely dissolved. Refrigerate, covered, until partially set.
In a bowl, beat cream until stiff peaks form. Fold into chilled rice mixture. Spoon into a 6-cup ring mold coated with cooking spray; refrigerate until firm, about 3 hours. Unmold onto a serving platter. Serve with strawberries.
