Add eggs, mix and combine.
Gradually add water and mix until a semi liquid and smooth batter is obtained..
Pour evenly the batter over the fruit in a pan. Cook covered over medium heat about 10 minutes.
When the cake is puffed and looks done, turn it out with the aid of a plate (like a tortilla).
Return the cake into the pan, uncooked side to the bottom. Sprinkle with 1 tablespoon icing sugar, cover and cook over medium heat additional 10-15mnutes.
Check for doneness with a toothpick (if it is dry and clean, remove the cake from the heat).
Let it cool and then turn out onto a plate, sprinkle with icing sugar.
