Ingredients
4 eggs, separated; 125g butter, melted, cooled, plus extra
for brushing; 200g (1 1/3 cups) plain flour, plus extra for dusting; 395g can sweetened
condensed milk; 250ml (1 cup) milk; 227g can crushed pineapple in juice; icing
sugar, to dust
Method
Preheat oven to 180⁰C/160⁰C fan-forced. Brush twelve, 160ml
(2/3 cup) muffin pans with butter and lightly dust with flour.
Use electric beaters to beat egg yolks in a large bowl for
3 to 4 minutes or until very pale and thick. Add the butter and beat until
combined. Add flour, beating until just combined. With the beaters on low
speed, gradually beat in the condensed milk and milk until well combined. Fold
in the pineapple.
Use clean beaters to whisk the egg whites in a bowl until
soft peaks form. Fold one-third of the egg whites into the flour mixture. Fold
in the remaining egg white, in two batches, until just combined.
Spoon the mixture evenly into the muffin pans. Bake for 20-
22 minutes or until the tops are firm but mixture is slightly wobbly. Set aside
in the pan to cool completely.
Serve the pies dusted with icing sugar.
