Whip the eggs, sugar, and salt until tripled in volume. Fold in the flour. Pour the mixture into a parchment lined 9 by 11-inch baking pan and bake for 25 to 30 minutes. Set aside to cool.
Remove the parchment paper and return the cake to the pan. With a fork, poke holes all over the top of the cake. Combine the condensed milk with the scalded milk, mango puree, almond and vanilla extracts, and pour over the cake. Allow the cake to soak in the liquid for 2 hours. Serve with diced mango marinated in dark rum and brown sugar.
