Preheat oven to 350°F (180°C).

In mixing bowl, beat together sugar, margarine and lime rind. Beat in egg yolks, one at a time, beating well after each addition. Beat in lime juice, then flour and milk.

In separate bowl, beat egg whites until still peaks form; fold into batter. Pour mixture into 9-inch (1.5 L) square baking dish. Place in larger pan; pour boiling water into outer pan to come about 1 inch (2.5 cm) up sides of pan.

Bake in preheated 350°F (180°C) oven until top is set and golden, about 40 minutes.

Spoon into serving dishes and top with berries. Serve warm or cold.
